Expresiones algebraicas: a) 2x + 5 = 20 b) x + 5 = 15 c) x - 8 = 12 d) x/3 = 5 e) 3x = 18 f) 2x + 3x = 40 g) 3x + 5 = 23 Despejar la incógnita: a) 10 + b = 18 b = 18 - 10 b = 8 b) c - 8 = 12 c = 12 + 8 c = 20 c) x + 12 = 24 x = 24 - 12 x = 12 d) 7 - x = 3 - x = 3 - 7 - x = - 4 x = 4 e) 7x = 21 x = 21/7 x = 3 f) 24x = 48 x = 48/24 x = 2 g) 7x + 3 = 31 7x = 31 - 3 7x = 28 x = 28/7 x = 4 h) 4 * 5 - x = 15 20 - x = 15 - x = 15 - 20 - x = - 5 x = 5 i) b/5 = 10 b = 10 * 5 b = 50 j) z/8 = 6 z = 6 * 8 z = 48
