Question

d) x – 23 + 12x = 7x – 21 + 32 e e) -5x + 20 -11x = -23 + 2x – 4

Answer 1

Oie, Td Bom?!

d)

x - 23 + 12x = 7x - 21 + 32

13x - 23 = 7x + 11

13x - 7x = 11 + 23

6x = 34

x = 34/6

x = 34÷2/6÷2

x = 17/3

e)

- 5x + 20 - 11x = - 23 + 2x - 4

- 16x + 20 = - 27 + 2x

- 16x - 2x = - 27 - 20

- 18x = - 47

x = - 47/-18

x = 47/18
