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 3c + 5 = 23?

Back

Subtract 5 from both sides to isolate the term with the variable: 3c = 18.

Front

What is the second step to solve the equation 3c + 5 = 23?

Back

Divide both sides by 3 to find c: c = 6.

Front

How do you isolate the variable in the equation 4x + 7 = 23?

Back

First, subtract 7 from both sides: 4x = 16.

Front

What is the final step to solve for x in the equation 4x + 7 = 23?

Back

Divide both sides by 4: x = 4.

Front

What does it mean to solve for a variable?

Back

To solve for a variable means to find the value of that variable that makes the equation true.

Front

Back

Multiply both sides by 9 to eliminate the fraction: 6 + z = 18.

Front

Back

Subtract 6 from both sides: z = 12.

Front

What is the first step to solve the equation 9 = 2s + 1?

Back

Subtract 1 from both sides: 8 = 2s.

Front

What is the final step to solve for s in the equation 9 = 2s + 1?

Back

Divide both sides by 2: s = 4.
