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

Solve for x: x + 13 = 25

Back

x = 12

Front

Solve for n: n - 4 = 12

Back

n = 16

Front

Solve for n: 5n = 30

Back

n = 6

Front

Solve for x: x - 10 = 20

Back

x = 30

Front

What operation would you use to isolate x in the equation x + 13 = 25?

Back

Subtract 13 from both sides.

Front

What operation would you use to isolate n in the equation n - 4 = 12?

Back

Add 4 to both sides.

Front

What is the first step to solve the equation 5n = 30?

Back

Divide both sides by 5.

Front

What is the solution to the equation m + 13 = 21?

Back

m = 8

Front

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

Back
