Answer:x=-4

Explanation:

First distribute -5 to x+4 so -5•x and -5•4 get you -5x and -20 then bring every thing down

Now you have

-12-5x-20=3x

Then combine like terms which are -12 and -20 giving you -32

-32-5x=3x and 5 to bot side now you have

-32=8x then divide by 8 on both side giving you -4
