Answer:

Y = 6

X = 24

Step-by-step explanation:

2x -5y = 16

(x -2y =5)*2

_______________

2x -5y = 16

2x - 4y = 10

_______________

(2x -5y = 16) - (2x - 4y = 10)

_______________

0x -y = 6

_______________

y =6

_______________

Replacing in equation 1:

2x - 5(6) = 16

so, 2x = 16 + 30

2x = 48

x = 24
