Answer:

x=-1

Step-by-step explanation:

I'm weird and love these types of problems.

Ok first off we need to get x alone. To do that we need to first get rid of the 7.

We can do that by adding it because you have to use the opposite operation to get rid of it.

5x - 7 (+7) = -12 (+7)

See if you add -7 + 7 you get 0 which is why you have to use the opposite.

5x = -5

To get x alone you have to divide 5 because 5 is being multiplied by x.

5x(/5) = -5(/5)

x= -1

So x= -1

If you ever need more help, don't be afraid to reach out. I hope that helps!
