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. It typically involves addition or subtraction followed by multiplication or division.

Front

Back

x = 18

Front

What is the inverse operation of subtraction?

Back

Addition

Front

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

Back

Subtract 11 from both sides.

Front

What is the second step when solving the equation: 2x - 14 = 34?

Back

Divide both sides by 2.

Front

To solve a simple two-step equation, what should you do first?

Back

Undo the Addition/Subtraction first (to remove the constant term), then undo the Multiplication/Division (to remove the coefficient and isolate the variable).

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 by itself, making it easier to solve.

Front

Back

x = 5.

Front

What is the first step to solve the equation: 5x - 10 = 15?

Back

Add 10 to both sides.

Front

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

Back

Inverse operations are used to 'undo' operations in order to isolate the variable and solve the equation.
