Sagot :
Answer:
x = -5
Step-by-step explanation:
Multiply each x and 3 by -4, obtaining
-4x - 12 = 8
Now solve for x by combining the constants:
-4x = 20, or
x = -5
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 ^_^
