Answer: x=-5
Step-by-step explanation: distribute the -4 first to both x and 3
-4x-12 = 8 then add 12 to both sides to isolate x
-4x= 20
divide by -4 and you get x= -5
check it
-4(-5+3)
-4(-5)= 20 (a negative times a negative makes a positive)
then -4(3)= -12
20-12= 8
it checks out, hope this helps ^_^
