What does it mean to isolate a variable in an equation?

Back

Isolating a variable means manipulating the equation to get the variable on one side of the equation by itself.

Front

What is the first step to solve the equation 4p = 20?

Back

Divide both sides by 4. The solution is p = 5.

Front

How do you solve the equation 11 - 3x = 44?

Back

Subtract 11 from both sides to get -3x = 33, then divide by -3 to find x = -11.

Front

What is the solution to the equation 4 - 2(x - 3) = 24?

Back

The solution is x = -7.

Front

What is the first step to solve the equation 3x - 10 = 5?

Back

Add 10 to both sides to get 3x = 15, then divide by 3 to find x = 5.

Front

How do you solve for w in the equation -6w + 1 = -11?

Back

Subtract 1 from both sides to get -6w = -12, then divide by -6 to find w = 2.

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single operation, such as addition, subtraction, multiplication, or division.

Front

What is a two-step equation?

Back

A two-step equation requires two operations to solve for the variable.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.
