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

How do you solve the equation x + 8 = 15?

Back

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

Front

What is the solution to the equation x - 10 = 40?

Back

Add 10 to both sides: x = 40 + 10, so x = 50.

Front

How do you solve the equation x + 22 = 53?

Back

Subtract 22 from both sides: x = 53 - 22, so x = 31.

Front

What is the solution to the equation x - 3.7 = 4.1?

Back

Add 3.7 to both sides: x = 4.1 + 3.7, so x = 7.8.

Front

How do you solve the equation x - 15 = 16?

Back

Add 15 to both sides: x = 16 + 15, so x = 31.

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 and all other terms are on the other side.

Front

What operation would you use to solve x + a = b?

Back

You would subtract 'a' from both sides to isolate x.

Front

What operation would you use to solve x - a = b?

Back

You would add 'a' to both sides to isolate x.

Front

What is the first step in solving x + 5 = 12?

Back

Subtract 5 from both sides: x = 12 - 5.
