You can put this solution on YOUR website! To find the value of c you need to multiply everything in the ( ) by 4. Then you solve for c :
8=4(3c+5) (Multiply the ( ) by 4)
8=(4*3c)+(4*5)
8=12c+20
(Now you need to get c by itself. Subtract 20 from both sides of the equations)
8-20=12c+20-20
-12=12c (Now divide each side of the equations by 12 to get c by itself)
-1=c
The value of c is -1
