2- Resolva as equações:

a) 4x - 1 = 3(x - 1) b) 3(x - 2) = 2x - 4 c) 2(2x - 1) = 3x + 4 d) 3(x - 1) - 7 = 15 e) 7(x - 4) = 2x - 3 f) 3(3x - 1) = 2(3x + 2) g) 7(x - 2) = 5(x + 3) h) 3(2x - 1) = 2(2x + 3) i) 5x - 3(x + 2) = 15 j) 2x + 3x + 9 = 8(6 - x)

3- Resolva as equações:

a) 3x - 7 = 2x + 5 b) 7x + 8 = 4x - 10 c) 4x - 15 = -2x + 3 d) 2x - 4 = -8 + 4 e) 3x = x + 1 + 7 f) 360 + 36x = 30x g) 5 + 6x = 5x = -1 h) 5 + 6x = 5x i) x + 2x - 1 = 3 = x j) -3x + 10 = 2x + 8 + 1
