Question

1. Encontre o valor da incógnita x

9(x-6)+14=5(x+12)-65

2) Encontre o valor de x

(2x+2)/2 + (3x+3)/3 =​

Answer 1

Explicação passo-a-passo:

1)

9(x-6) + 14 = 5(x + 12) - 65

9x - 54 + 14 = 5x + 60 - 65

9x - 5x = +60 +54 - 65 - 14

4x = 114 - 79

4x = 35

x = 35/4

2)

(2x + 2)/2 + (3x + 3)/3 = 0

2(x+2)/2 + 3(x+3)/3 = 0

x + 1 + x + 1 = 0

2x + 2 = 0

2x = -2

x = -2/2

x = -1
