Explicação passo a passo:

a, 7x - 35 = 3x +3 <=> 7x - 3x = 3 + 35 <=> 4x = 38 <=> x = 19/2

b, 3x - 6 = -4x +12 <=> 3x + 4x = 12 + 6 <=> 7x = 18 <=> x = 18/7

c, 2x + 2 - x + 1 = 0 <=> ( 2x - x ) + ( 2+1 ) =0 <=> x = -3

d, 5x + 5 - 3x - 6 = 0 <=> (5x + 3x) + (5 - 6) = 0 <=> 8x = 1 <=> x = 1/8

e, 13 + 8x - 4 = 5x + 10 <=> 8x - 5x = 10 -13 + 4 <=> 3x = 1 <=> x = 1/3

f, 4x + 20 + 3x + 15 = 21 <=> 7x = -14 <=> x = -2

g, 2x + 10 -3 - 5 + x =0 <=> 3x = -2 <=> x = -2/3

h, 8x - 8 = 8 - 8x + 12 <=> 8x + 8x = 8 + 12 + 8 <=> 16x = 28 <=> x = 7/4
