Question

(2x+7,5y-9) (x+3,3y-3)

Answer 1

Boa tarde Felipe

(2x + 7,  5y - 9) (x + 3, 3y - 3)

2x + 7 = x + 3
2x - x = 3 - 7

x = -4

5y - 9 = 3y - 3
5y - 3y = -3 + 9
2y = 6

y = 3

Answer 2

(2x + 7,5y - 9) (x + 3,3y - 3)

(x ; y)  (x ; y)

2x + 7 = x + 3
2x - x = 3 - 7
x = - 4

5y - 9 = 3y - 3
5y - 3y = - 3 + 9
2y = 6
y = 6/2
y = 3

Resp.: ( - 4 ; 3)
