8: x=2 as 15x-21-18x+22=32x+52-17
-3x+1-32x=-69-1
-35x=-70


10: t=2
11: x=-1

8 → 3(5x-7)-2(9x-11) = 4(8x-13)-17

or, 15x-21 - 18x+22 = 32x-52-17

or, -3x + 1 = 32x-69

or 1+69 = 32x + 3x

or, 70 = 35x

or, x = 70/35

or, x = 2

_______________________________

10→ (3t-2)/4 - (2t+3)/3 = 2/3 - t

or,{ 3(3t-2)-4(2t+3)}/12 = (2-3t)/3

or, {(9t-6)-(8t+12)}/12 = (2-3t)/3

or, (9t-6-8t-12)/12 = (2-3t)/3

or, (t-18)/12 = (2-3t)/3

or, 3(t-18) = 12(2-3t)

or, 3t - 54 = 24-36t

or, 3t+36t = 24+54

or, 39t = 78

or, t = 78/39

or, t = 2

___________________________________

11→ (2x+7)/5 - (3x+11)/2 = 2x+8/3 - 5

or, {2(2x+7)-5(3x+11)}/10 = (2x+8 - 15)/3

or, {(4x+14)-(15x+55)/10 = (2x-7)/3

or, (4x+14-15x-55)/10 = (2x-7)/3

or,( -11x - 41)/10 = (2x-7)/3

or, 3(-11x-41) = 10(2x-7)

or, -33x - 123 = 20x - 70

or, -33x - 20x = -70+123

or, -53x = 53

or, x = 53/-53

or, x = -1
