-9

x . 9 =12-3x9x =12-3x9x+3x=1212x =12x =1

Well if 3x+9=5 x=? Well you minus 9 from the side and then do 5-9 and that equals -4. Then you have to do -4 divided by 3. Which equals -1 so I believe x will equal -1.

Watch closely:6x = 3x + 27Subtract 3x from each side:3x = 27Divide each side by 3:x = 9

Solve this problem -x squared -40x- 80 =0
