One and Two Step Equations

Front

What is a one-step equation?

Back

An equation that can be solved in one step, typically by performing a single operation (addition, subtraction, multiplication, or division) to isolate the variable.

Front

What is a two-step equation?

Back

An equation that requires two steps to solve, usually involving two operations to isolate the variable.

Front

Solve the equation: 5x = 25

Back

x = 5

Front

Solve for x: x + 12 = 20

Back

x = 8

Front

Solve for c: 4c - 5 = 23

Back

c = 7

Front

Solve for x: x - 8 = 5

Back

x = 13

Front

What is the first step to solve the equation x + 12 = 20?

Back

Subtract 12 from both sides of the equation.

Front

What is the first step to solve the equation 4c - 5 = 23?

Back

Add 5 to both sides of the equation.

Front

What does it mean to isolate a variable?

Back

To manipulate an equation so that the variable is on one side and all other terms are on the opposite side.

Front

What operation would you use to solve the equation 5x = 25?

Back

Division, to divide both sides by 5.
