Question

me ajudeem, por favor

Answer 1

Resposta:

Explicação passo-a-passo:

A)

(5x-10)/2 = 10 - (5x-5)/3

Mmc (2,3)= 6

[3.(5x-10)]/6 = [6.10 - 2.(5x-5)]/6

15x-30 = 60 - 10x + 10

15x +10x = 70+30

25x = 100

x = 100/25

x = 4

B)

- x/2 - x/3=2/3

Mmc(2,3) = 6

(- 3x - 2x )/3= 2.2/6

- 5x = 4

x = - 4/5
