Solve Two Step Equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

What is the first step to solve the equation 6(x+2) = 18?

Back

Distribute the 6 to both terms inside the parentheses: 6x + 12 = 18.

Front

What is the second step to solve the equation 6x + 12 = 18?

Back

Subtract 12 from both sides: 6x = 6.

Front

How do you isolate the variable in the equation 6x = 6?

Back

Divide both sides by 6: x = 1.

Front

What is the solution to the equation 4(x-9) = -16?

Back

x = 5.

Front

What is the first step to solve the equation 4(x-9) = -16?

Back

Distribute the 4: 4x - 36 = -16.

Front

What do you do after distributing in the equation 4x - 36 = -16?

Back

Add 36 to both sides: 4x = 20.

Front

How do you solve for x in the equation 4x = 20?

Back

Divide both sides by 4: x = 5.

Front

What is the solution to the equation 3(x+5) = 21?

Back

x = 2.

Front

What is the first step to solve the equation 3(x+5) = 21?

Back

Distribute the 3: 3x + 15 = 21.
