One Step Equations (Adding and Subtracting)

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step, typically by adding or subtracting a number from both sides.

Front

Solve for x: x - 12.5 = 10,542

Back

x = 12,554.5

Front

Solve for x: x - 2.3 = 19.5

Back

x = 21.8

Front

Solve for x: x + 5 + 6 = 15

Back

x = 4

Front

Solve for x: x + 4 = 12

Back

x = 8

Front

Solve for x: 66 = x + 1

Back

x = 65

Front

What is the first step to solve x + 4 = 12?

Back

Subtract 4 from both sides to isolate x.

Front

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

Back

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

Front

If x + 5 = 15, what is x?

Back

x = 10

Front

If 10,542 = x - 12.5, how do you find x?

Back

Add 12.5 to both sides of the equation.
