First use the distributive property to multiply out the right side of the equation.
8=12c+20
Then subtract 20 from both sides
-12=12c
Finally, divide both sides by 12
-1 = c

Hey Not a problem ! Hope this helps!!
8= 4(3c+5)
8 = 12c + 20
8 - 20 = 12c
-12=12c
c= -1
First you need to multiply 4 times (3c+5) then you need to pass 20 to the other side substracting, then you pass the 12 dividing and that's all!!

8=12c+20
= 12c+20-8
= 12c+12
= 12(c+1)
