c = 6 and d = 7
It equals 24.

144 9+7 = 16 and 9*16 = 144
144 9+7 = 16 and 9*16 = 144
3d + 8 = 2d - 7 3d -2d = -8 - 7 1d = - 15 d = -15
c = 6 and d = 7
3d+8=2d-7 3d+8-8=2d-7-8 (substract 8 on both side) 3d=2d-15 3d-2d=2d-2d-15 (substract 2d on both side) d=-15
It equals 24.

2(3d+7)=5+5d. 6d+14=5+5d 6d+9=5d 9=-1d d=-9 I think that's correct. If it is, ur welcome.
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
If I am correct, 9 plus 7 equals 112.
