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 -6w + 1 = -11?

Back

Subtract 1 from both sides to isolate the term with the variable.

Front

Solve for w: -6w + 1 = -11.

Back

w = 2.

Front

What is the first step to solve the equation 9 + 3x = 10?

Back

Subtract 9 from both sides.

Front

Solve for x: 9 + 3x = 10.

Back

x = rac{1}{3}.

Front

What is the first step to solve the equation -4 = 2t - 2?

Back

Add 2 to both sides.

Front

Solve for t: -4 = 2t - 2.

Back

t = -1.

Front

What is the first step to solve the equation -11 - 3x = 44?

Back

Add 11 to both sides.

Front

What is the solution to the equation 9 = 2s + 1?

Back

s = 4.

Front

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

Back

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