Back

A one-step equation is an algebraic equation that can be solved in a single step, typically involving addition or subtraction.

Front

How do you solve the equation n - 3 = 28?

Back

Add 3 to both sides: n = 28 + 3, so n = 31.

Front

What is the solution to the equation n + 23 = 85?

Back

Subtract 23 from both sides: n = 85 - 23, so n = 62.

Front

How do you solve the equation 71 = s + 38?

Back

Subtract 38 from both sides: s = 71 - 38, so s = 33.

What is the solution to the equation x - 7 = 2?

Back

Add 7 to both sides: x = 2 + 7, so x = 9.

Front

How do you solve the equation 41 = 3 + x?

Back

Subtract 3 from both sides: x = 41 - 3, so x = 38.
