Question

Urgent! j) si k) va rog

Answer 1

Răspuns:

Explicație pas cu pas:

j)

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

5(3x + 2) = 10(x + 2)

15x + 10 = 10x + 20

15x - 10x = 20 -10

5x = 10

x = 2

_________________

k)

(x + 1)(2x + 4)/(x + 2) = 12

(x + 1)*2(x + 2)/(x + 2) = 12

2(x + 1) = 12

x + 1 = 6

x = 5
