Solving One-Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step by performing the same operation on both sides of the equation.

Front

How do you solve the equation x - 8 = -5?

Back

Add 8 to both sides: x = -5 + 8, so x = 3.

Front

What is the solution to the equation n + 4.7 = -4.7?

Back

Subtract 4.7 from both sides: n = -4.7 - 4.7, so n = -9.4.

Front

How do you solve the equation x - 7.09 = -10.89?

Back

Add 7.09 to both sides: x = -10.89 + 7.09, so x = -3.8.

Front

What is the solution to the equation n/12 = 4?

Back

Multiply both sides by 12: n = 4 * 12, so n = 48.

Front

How do you solve the equation -2 + x = 15?

Back

Add 2 to both sides: x = 15 + 2, so x = 17.
