Solving One Step Equations

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 = -5?

Back

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

Front

What is the solution to the equation 10 = -7 + b?

Back

Add 7 to both sides: 10 + 7 = b, so b = 17.

Front

How do you solve the equation x - (-1) = 11?

Back

Rewrite as x + 1 = 11, then subtract 1 from both sides: x = 10.

Front

What is the solution to the equation x + 12 = 20?

Back

Subtract 12 from both sides: x + 12 - 12 = 20 - 12, so x = 8.

Front

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

Back

Subtract 5 from both sides.

Front

What does it mean to 'isolate the variable' in an equation?

Back

To isolate the variable means to get the variable alone on one side of the equation.

Front

If x - 4 = 6, what is x?

Back

Add 4 to both sides: x = 10.

Front

What is the first step to solve the equation 3x = 12?

Back

Divide both sides by 3.

Front

How do you solve the equation x/4 = 2?

Back

Multiply both sides by 4: x = 8.
