find the value of x (5x+12) (3x+8) a 10 b 15 c 20 d 25

(5x+12)+(3x+8)=180 combine likes terms 5x+3x=8x 12+8=20 rewrite
8x+20=180 subtract 20 from both sides 180-20=160 rewrite 8x=160 then divide 8 from both sides 160/8=20 rewrite X=20, so C is your answer
Hope this helps have a lovely nite, and a good Friday and good week and good year!!! Good luck in school!
