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 by performing the same operation on both sides of the equation.

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 by itself, making it easier to solve.

Front

Solve for b: 4 + b = 30

Back

b = 26

Front

Solve for y: y + 51 = 99

Back

y = 48

Front

Solve for x: -4 - x = 6

Back

x = -10

Front

Solve for x: x - 32 = 49

Back

x = 81

Front

Solve for x: x + 12 = 20

Back

x = 8

Front

What operation would you use to solve the equation x + 5 = 12?

Back

You would subtract 5 from both sides of the equation.

Front

What operation would you use to solve the equation y - 7 = 15?

Back

You would add 7 to both sides of the equation.

Front

If x + 10 = 25, what is x?

Back

x = 15
