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 for x: 2x + 3 = 11

Back

x = 4

Front

What is the first step to solve the equation 5x - 7 = 18?

Back

Add 7 to both sides to isolate the term with x.

Front

Solve for c: 3c + 5 = 23

Back

c = 6

Front

What does it mean to isolate a variable?

Back

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

Front

Solve for x: x/7 - 2 = 8

Back

x = 70

Front

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

Back

Subtract 9 from both sides to isolate the term with x.

Front

Solve for x: 9 + 3x = 10

Back

x = 1/3

Front

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

Back

Inverse operations are used to undo operations and isolate the variable.

Front

Solve for x: x/5 - 13 = 20

Back

x = 165
