- 3 = 12
subtract 3
divide by 3
add 3
o multiply by 3

add 3 to both sides of the equal sign

Step-by-step explanation:

that is because you have to do inverse operations

and you would add because the opposite of subtracting is adding

so solving it would look like this

x - 3 = 12

x = 15

this is how you check the

15 - 3 = 12

    +3   +3
