2(4x-3d)+3(d-6x+5)-4(9+8x-12d) = 8x - 6d + 3d - 18x +15 -36 -32x + 48d = 45d - 42x -21
We cannot solve for x and d in the absence of any equations

= 8x - 6d + 3d - 18x + 15 - 36 - 32x + 48d
= - 42x + 45d - 21
= - 3 (14 x - 15 d + 7)

8x-6d+3d-15x+15-36-32x+48d
=8x-18x-32x-6d+3d+48d+15-36
=-42x+45d-21

8x-6d+3d-18x+15-36-32x+48d
45d-42x-21
3(15d-14x-7)

(8x-6d)+(3d-18x+15)-(36+32x-48d)
(-12x-3d+15)-(36+32x-48d)
(-48x+45d+51)
48x-45d-51
just simplified your equation..
