Step 1: Use the inverse operation to get the variable by itself
To undo multiplying by 3, we need to divide both sides by 3.
Step 2: Check your answer
Plug 4 in for x in the original equation. 3(4) = 12, this means 4 is the correct answer.
Equations with Division
To undo division, we need to use multiplication. Next, let's take a look at a one-step equation with division involved:
Step 1: Use the inverse operation to get the variable by itself
To undo dividing by 2, we need to multiply by 2.
Step 2: Check your answer
Take your answer and plug it in for x in the original equation. Does 10 divided by 2 equal 5? Yes. This means our answer is correct.
