Question

x + 9-18
x-1= -8
7x+ 5 - 68 - 2x
14 - 3x - 2x + 29
8x - 9 - 2x + 11​

Answer 1

Resposta:

a) x = 18 - 9

x = 9

b) x = -8 + 1

x = -7

C) 7x - 2x = 68 - 5

5x = 63

x = 63/5

x = 12,6

d) - 5x = - 29 - 14

- 5x = - 43

multiplique por (-1)

5x = 43

x = 43/5

x = 8,6

e) 8x - 2x = 9 - 11

6x = - 2

x = - 2/6

x = - 0,333...
