Question

URGENTE!!! Resolva:

a) x/4 + 5 = x/2 + 6

b) x-4/3 + 2x-1/2 = 2

Answer 1

Resposta:

Explicação passo-a-passo:

a)

x/4 + 5 = x/2 + 6

x/4 - x/2 = 6 - 5

x/4 - x/2 = 1

(x - 2x)/4 = 4/4

x - 2x = 4

- x = 4 (-1)

x = - 4

b)

x - 4/3 + 2x - 1/2 = 2

3x = 2 + 1/2 + 4/3

6.3x/6 = (6.2 + 3 + 2.4)/6

18x = 12+3+8

18x = 15+8

18x = 23

x = 23/18
