Solving 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 - 3a = 21?

Back

Subtract 6 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation 6 - 3a = 21 after isolating the variable term?

Back

Divide both sides by -3 to solve for 'a'.

Front

Solve the equation: -4x + 1 = 21

Back

x = -5

Front

What is the solution to the equation 2x - 3 = 1?

Back

x = 2

Front

How do you isolate 'v' in the equation 8 = 4v + 12?

Back

Subtract 12 from both sides and then divide by 4.

Front

What is the solution to the equation 8 = 4v + 12?

Back

v = -1

Front

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

Back

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

Front

What is the purpose of solving two-step equations?

Back

The purpose is to find the value of the variable that makes the equation true.
