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

How do you solve the equation b + 6 = 14?

Back

Subtract 6 from both sides: b = 14 - 6, so b = 8.

Front

What is the solution to the equation x + 5 = 12?

Back

Subtract 5 from both sides: x = 12 - 5, so x = 7.

Front

How do you find the value of z in the equation z + 10 = 25?

Back

Subtract 10 from both sides: z = 25 - 10, so z = 15.

Front

What number should be subtracted from 20 to get 12?

Back

Subtract 8 from 20: 20 - 8 = 12.

Front

What is the process to solve x - 3 = 5?

Back

Add 3 to both sides: x = 5 + 3, so x = 8.

Front

How do you solve the equation 15 = y + 7?

Back

Subtract 7 from both sides: y = 15 - 7, so y = 8.

Front

What is the solution to the equation 30 - z = 22?

Back

Subtract 22 from 30: z = 30 - 22, so z = 8.

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.

Front

How do you check the solution of an equation?

Back

Substitute the solution back into the original equation to see if both sides are equal.
