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 8x - 6x + 4 + 5 = 19?

Back

Combine like terms: 2x + 9 = 19.

Front

How do you isolate the variable in the equation 2x + 9 = 19?

Back

Subtract 9 from both sides: 2x = 10.

Front

What is the final step to solve for x in the equation 2x = 10?

Back

Divide both sides by 2: x = 5.

Front

What does it mean to 'isolate the variable'?

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

Solve for x: x/4 - 3 = 9

Back

x = 48.

Front

What is the first step to solve the equation x/4 - 3 = 9?

Back

Add 3 to both sides: x/4 = 12.

Front

What is the final step to solve for x in the equation x/4 = 12?

Back

Multiply both sides by 4: x = 48.

Front

Solve for v: 8v - 4(v + 8) = 8

Back

v = 10.

Front

What is the first step to solve the equation 8v - 4(v + 8) = 8?

Back

Distribute -4: 8v - 4v - 32 = 8.
