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: 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

Solve for x: 4x + 7 = 23.

Back

x = 4.

Front

What is the first step to solve the equation: 9m - 4 = 23?

Back

Add 4 to both sides.

Front

Solve for t: 5t + 3 = 28.

Back

t = 5.

Front

What do you do to isolate the variable in a two-step equation?

Back

You perform inverse operations to both sides of the equation.

Front

If you have the equation 3m - 4 = 11, what is the first step?

Back

Add 4 to both sides.

Front

Solve for m: 3m - 4 = 11.

Back

m = 5.

Front

What is the purpose of using inverse operations in solving equations?

Back

To isolate the variable and find its value.

Front

What does it mean to 'isolate the variable'?

Back

To get the variable alone on one side of the equation.
