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

Solve: 3c + 5 = 23

Back

c = 6

Front

What is the first step to solve the equation 2d + 7 = 9?

Back

Subtract 7 from both sides to isolate the term with the variable.

Front

Solve: 2d + 7 = 9

Back

d = 1

Front

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

Back

To isolate a variable means to get the variable alone on one side of the equation.

Front

Solve: x/7 - 2 = 8

Back

x = 70

Front

What is the second step to solve the equation x/12 - 8 = -4?

Back

Add 8 to both sides to isolate the term with x.

Front

Solve: x/12 - 8 = -4

Back

x = 48

Front

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

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.

Front

Solve for a: 2a - 4 = 8

Back

a = 6
