12d -9 = 15d +9subtract 12d from each side and add 9 to each side0= 3ddivide by 3 on each side0 = d.because if zero is in the numerator or dominator it makes the faction 0.
(d - 8)(d - 4)
12d - 9 = 15d + 9 Subtract 15 d from both sides: -3d - 9 = 9 Add 9 to both sides: -3d = 18 Divide both sides by -3: d = -6
