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: 2w + 3 = 15?

Back

Subtract 3 from both sides to isolate the term with the variable.

Front

Solve for w: 3w - 5 = 13.

Back

w = 6.

Front

What is the purpose of isolating the variable in an equation?

Back

To find the value of the variable that makes the equation true.

Front

Solve for a: 4a + 8 = 0.

Back

a = -2.

Front

What does it mean to 'balance' an equation?

Back

To perform the same operation on both sides of the equation to maintain equality.

Front

Solve for n: n/2 + 7 = 10.

Back

n = 6.

Front

What is the second step to solve the equation: 5a = 25?

Back

Divide both sides by 5.

Front

Solve for a: 2a - 3 = 5.

Back

a = 4.

Front

What operation would you perform first to solve: 3x + 4 = 10?

Back

Subtract 4 from both sides.
