Franco Cooke · Answer 1

the answer is property of division

Step-by-step explanation:

look at step 4 then compare it to step 5 how 12 got divided by

Marisol Buckley · Answer 2

In step four, you'd divide each side by - 2 to isolate x

By dividing both sides by - 2, you are using the property of equality and it gets you to the answer in Step 5.
