Question

1)Resolva as equações
a) 6x = 2x + 16 b) 2x – 5 = x + 1 c) 2x + 3 = x + 4 d) 5x + 7 = 4x + 10 e) 4x – 10 = 2x + 2 f) 4x – 7 = 8x – 2 g) 2x + 1 = 4x – 7 h) 9x + 9 + 3x = 15 i) 16x – 1 = 12x + 3 j) 3x – 2 = 4x + 9 l) 5x -3 + x = 2x + 9 m) 17x – 7x = x + 18 n) x + x – 4 = 17 – 2x + 1 o) x + 2x + 3 – 5x = 4x – 9 p) 5x + 6x – 16 = 3x + 2x - 4 q) 5x + 4 = 3x – 2x + 4
2) Resolva as seguintes equações a) 2x + 5 - 5x = -1 b) 5 + 6x = 5x + 2 c) x + 2x - 1 - 3 = x d) -3x + 10 = 2x + 8 +1 e) 5x - 5 + x = 9 + x f) 7x - 4 - x = -7x + 8 - 3x g) -x -5 + 4x = -7x + 6x + 15 h) 3x - 2x = 3x + 2 i) 2 - 4x = 32 - 18x + 12 j) 2x - 1 = -3 + x + 4 l) 3x - 2 - 2x - 3 = 0 m) 10 - 9x + 2x = 2 - 3x n) 4x - 4 - 5x = -6 + 90 o) 2 - 3x = -2x + 12 - 3x
