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 4x + 7 = 23?

Back

Subtract 7 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation 4x = 16?

Back

Divide both sides by 4 to find the value of x.

Front

Solve the equation: 4x + 7 = 23

Back

x = 4

Front

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

Back

Isolating a variable means to manipulate the equation so that the variable is on one side by itself.

Front

What is the first step to solve the equation 12 = 4 - 4x?

Back

Add 4x to both sides to move the variable term to one side.

Front

What is the second step to solve the equation 4 - 4x = 12?

Back

Subtract 4 from both sides to simplify the equation.

Front

Solve the equation: 12 = 4 - 4x

Back

x = 4

Front

What is the solution to the equation 5x + 4 = -6?

Back

x = -2

Front

What is the first step to solve the equation -3x + 5 = -16?

Back

Subtract 5 from both sides to isolate the term with the variable.
