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.

Front

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

Back

w = 2

Front

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

Back

Add 11 to both sides.

Front

Solve for x: 4x + 7 = 23

Back

x = 4

Front

What is the first step to solve the equation 2n + 10 = -2?

Back

Subtract 10 from both sides.

Front

Solve for n: 2n + 10 = -2

Back

n = -6

Front

What is the first step to solve the equation 6z + 3 - 4z = 9?

Back

Combine like terms.

Front

Solve for z: 6z + 3 - 4z = 9

Back

z = 3

Front

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

Back

Isolating the variable means to manipulate the equation so that the variable is on one side and all other terms are on the other side.
