I really like this Mathematics question :)

xy = -4

step-by-step explanation:

"a soma de um numero x com o dobro de um numero y e -7"

x + 2y = -7

"a diferenca entre o triplo desse numero x e numero y e igual a 7"

3x - y = 7

x + 2y = -7

3x - y = 7     > * 2

      x + 2y = -7

+     6x - 2y = 14

      7x         = 7

        x         = 1

x + 2y = -7

1 + 2y = -7

2y = -8

y = -4

xy = 1 * (-4) = -4
