Front

How do you solve the equation h + 68 = 166?

Back

To solve for h, subtract 68 from both sides: h = 166 - 68, which gives h = 98.

Front

What is the purpose of using variables in algebra?

Back

Variables are used to represent unknown values and allow us to write general formulas and equations.

Front

What does it mean to 'undo' an addition operation?

Back

To 'undo' an addition operation means to perform the inverse operation, which is subtraction.

Front

What is the solution to the equation x + 15 = 30?
