A) -12x+8(5-6)=1-8(x-9)+8
-12x+8(-1)= 1-8x+72+8
-8-1-80= -8x+12x
-89=4x
x= -4/89
B) 3x-19=18-6x
3x+6x=18+19
9x=37
x=37/9
C) 3x - 24 (15x + 8) =12x - (25x - 36)
3x-360x+192=12x-25x+36
3x-360x+13x=36-192
-344x=-156
x=39/86
D)5/8 x - 6/7 = 4/3 - 12
5/8x-4/3x=-12+6/7
-17/24x=-78/7
x=119/1872
E) 25(2x - 28) = 12(4 + 2x)
50x-700=48+24x
50x-24x=48+700
26x=748
x=374/13
F) 5/2 (2 - 3/4 x) - 3/2 = 12x + 8/5
5-15/8x-3/2=12x+8/5
5-3/2-8/5=8/5x+15/8x
19/10=139/40x
x=139/76
