One Step Equations Addition and Subtraction

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 12 = x + 7?

Back

Subtract 7 from both sides: x = 12 - 7, so x = 5.

Front

What is the solution to the equation -3 + x = 8?

Back

Add 3 to both sides: x = 8 + 3, so x = 11.

Front

How do you solve the equation v - 35 = 44?

Back

Add 35 to both sides: v = 44 + 35, so v = 79.

Front

What is the solution to the equation s - 17 = 87?

Back

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

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 get the variable alone on one side of the equation to find its value.

Front

What operation would you use to solve x + 10 = 15?

Back

You would subtract 10 from both sides to isolate x.

Front

What is the first step to solve the equation 5 = y - 3?

Back

Add 3 to both sides to isolate y.

Front

What is the solution to the equation 20 = z + 5?

Back

Subtract 5 from both sides: z = 20 - 5, so z = 15.
