One Step Equation Easy

Which of the following are important to remember when solving equations?

• Whatever you do to one side of the equal sign, you do the same thing on the other side.

• The goal is to get the variable on the left side of the equal sign

• We need to undo the operation being shown by using the inverse (or opposite) operation.

• Whatever you do to one side of the equal sign, you do the opposite on the other side.

• The goal is to get the variable alone on one side of the equal sign.

• Add 15 on both sides of the equal sign.

• Subtract 15 on both sides of the equal sign.

• Add 15 on the left side of the equation and subtract 15 on the right side of the equal sign.

• Subtract 15 on the left side of the equation and add 15 on the right side of the equal sign.

• Multiply by 5 on both sides of the equal sign.

• Divide by 5 on both sides of the equal sign.

• Multiply by 5 on the left side of the equation and divide by 5 on the right side of the equal sign.

• Divide by 5 on the left side of the equation and multiply by 5 on the right side of the equal sign.

Solve x + 5 = 15

Remember to practice writing out the steps even if it is easy.

x = _____

Solve for x:
