PUNTO 18

a) 2x + [img = 44] = [img = 45] 2x - [img = 46] = - [img = 47] [img = 48] = - [img = 49] 3(10x) = 7( - 4) 30x = - 28 x = - [img = 50] y simplificando es igual a [img = 51]

b) [img = 52] - 7 = - [img = 53] - 3 [img = 54] + [img = 55] = 7 - 3 [img = 56] = 4 17x = 4(10) 17x = 40 x = [img = 57] c) x - [img = 58] + 6 = [img = 59] x - [img = 60] = [img = 61] - 6 [img = 62]÷ x = - [img = 63] 3([img = 64] - 5) = 3 ( - 8) [img = 65] - 15 = - 24 [img = 66] = 15 - 24 [img = 67] = - 9 [img = 68] = [img = 69] [img = 70] = - 3 [img = 71]

d) [img = 72] + [img = 73] = x - [img = 74] [img = 75] + [img = 76] 2(47) = 10( - 5x)

94 = - 50x

x = - [img = 77] simplificando queda - [img = 78].
