Front

What is a one-step equation?

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 m - 432 = 274?

Back

Add 432 to both sides: m = 274 + 432, so m = 706.

Front

What is the solution to the equation n - (-3) = 28?

Back

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

Front

How do you solve the equation s - 17 = 87?

Back

Add 17 to both sides: s = 87 + 17, so s = 104.

Front

What is the solution to the equation s + 38 = -22?

Back

Subtract 38 from both sides: s = -22 - 38, so s = -60.

Front

How do you solve the equation n + 85 = 23?

Back

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

Front

What does it mean to isolate the variable in an equation?

Back

Isolating the variable means to manipulate the equation so that the variable is on one side and all other terms are on the other side.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.
