Multiplying Equations

Question 1

In order to solve an equation, we will use the strategy of inverse operation.

Inverse operation is the ____________ operation and it helps us to isolate the variable (get the variable alone).

The inverse of multiplication is __________ because it will undo multiplication.

Answer 1

In order to solve an equation, we will use the strategy of inverse operation.

Inverse operation is the opposite operation and it helps us to isolate the variable (get the variable alone).

The inverse of multiplication is division because it will undo multiplication.

Question 2

Steps:

1.) Find the inverse operation of the number on the same side of the equation as the variable. Look for the ______________ !

2.) Divide ______ sides of the equation to isolate the variable. We will be showing division in the format of a fraction.

3.) Check your answer by substituting your solution in the original equation to see if it makes the equation ________.

Answer 2

Steps:

1.) Find the inverse operation of the number on the same side of the equation as the variable. Look for the coefficient!

2.) Divide both sides of the equation to isolate the variable. We will be showing division in the format of a fraction.

3.) Check your answer by substituting your solution in the original equation to see if it makes the equation true.
