Equations for those who don't like Math

Explore how an equation captures a question in the mathematical language, as shown by two plus what is five. See that ten minus what is eight yields the answer two.

Learn how mathematics uses the letter X as a variable to form equations like ten minus X equals eight, and solve for X.

Demonstrate how to solve simple equations by finding an x that balances the left and right sides, as in 10 minus 2 equals 8 and 2 plus 3 equals 5.

Demonstrate how the equal sign requires both sides to match, then show how adding the same number to both sides keeps five equals five turning into six equals six.

Subtract a number from an equation to maintain balance, as in seven equals seven. Subtract two from both sides to preserve equality and solve the equation.

Learn how solving equations means finding x so both sides stay equal, using simple and scalable methods from easy examples like x+2=5 to x+568=749.

Master solving any equation by leaving X alone on the left, subtracting two to cancel it, and balancing both sides to find X equals the solution.

Master solving equations by isolating x on the left and subtracting the same value from both sides, demonstrated with x + 5 = 7 to get x = 2.

Isolate x by subtracting two from both sides and rearranging terms. Recognize that the order of plus and minus terms doesn't matter, and conclude x equals four.

solve simple linear equations by isolating x using addition and subtraction on both sides, with four worked examples and quick checks to confirm each solution.

Switch the sides of an equation when x is on the right; this makes ten equals x plus two the same as x plus two equals ten.

Isolate x by subtracting two from both sides. The equation resolves to x equals eight.

Learn to solve simple equations by swapping sides and subtracting to isolate x, as shown in two easy examples.

This example demonstrates keeping X alone on the left by adding one to both sides, turning minus one plus one into zero and leaving X with no operator.

Turn subtraction into addition by using negative numbers: eight minus four equals eight plus negative four, and twenty minus twelve equals twenty plus negative twelve, explained on a blank page.

Replace minus one with plus minus one to maintain the equation. Simplify to x plus zero equals five, and conclude x equals five.

Isolate x by adding four to both sides, using the plus minus four trick, and conclude x equals seven.

Solve for x in two linear equations by adding the same number to both sides to cancel a minus term, yielding x equals five.

Solve equations by isolating x with pluses and minuses, moving terms across the equation, and switching signs when faced with minus x to reveal x equals minus four.

See another example of solving for x by canceling terms on both sides and switching signs to isolate x, yielding x equals 3.

Learn to solve linear equations with minus x by isolating x and switching signs on both sides, illustrated by two examples yielding x equals minus one and x equals three.

Learn to solve equations by keeping x alone on the left and removing x from the right, using x+1 minus x and x+x minus x until x equals one.

Explains how 2x represents x plus x, and shows how to move terms to the left and subtract x from both sides to solve for x.

Move all x terms to the left and constants to the right, then subtract like terms to isolate x and solve equations with x on both sides.

Move all x terms to the left and cancel terms on both sides to isolate x in linear equations. Practice solving examples such as x+1=4 and 2+x=4 to find x.

Move x terms to the left, subtract x to get two x equals ten, then divide by two to find x equals five, illustrating multiplication and division concepts.

Solve linear equations by grouping like terms and isolating x on the left, then divide both sides by eight to get x = 1.

Move x terms to the left and constants to the right to isolate x, then divide to solve the linear equation. The solution is x equals three.

Explore solving linear equations by moving x terms to the left, constants to the right, subtracting on both sides, and dividing to isolate x, with examples using larger numbers.
