Solve 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 t - 24 = 89?

Back

Add 24 to both sides: t = 89 + 24, so t = 113.

Front

What is the solution to the equation x + 23 = -45?

Back

Subtract 23 from both sides: x = -45 - 23, so x = -68.

Front

What is the first step to solve m - 14 = 76?

Back

Add 14 to both sides: m = 76 + 14, so m = 90.

Front

How do you isolate the variable in the equation 142 = j + 204?

Back

Subtract 204 from both sides: j = 142 - 204, so j = -62.

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 other side.

Front

What operation would you use to solve the equation x - 5 = 10?

Back

Add 5 to both sides: x = 10 + 5, so x = 15.

Front

What is the solution to the equation 3y = 12?

Back

Divide both sides by 3: y = 12 / 3, so y = 4.

Front

How do you solve the equation 5 = z + 2?

Back

Subtract 2 from both sides: z = 5 - 2, so z = 3.

Front

What is the solution to the equation -x = 7?

Back

Multiply both sides by -1: x = -7.
