Answer:

x=-7

Step-by-step explanation:

Subtract 5 from both sides.

−x=12−5

Subtract 5 from 12 to get 7.

−x=7

Multiply both sides by −1.

x=−7

Answer:

x = -7

Step-by-step explanation:

When subtracting negative numbers from positive it's like adding. The rules are a bit wonky I know haha. So your problem would look like this when "x" is solved:

5 - -7 = 12

Hope this helps and have a nice day!
