Answer:
x = -20 , y = -44/5
Step-by-step explanation:
2x = 5у + 4
x = (5у + 4)/2 ______1
3х - 2y + 16 = 0
3{(5y+4)/2} - 2y + 16 = 0 (from 1)
(15y +12)/2 - 2y = -16
(15y + 12 -10y)/2 = -16
(5y+12)/2 = -16
5y + 12 = -32
5y = -44
y = -44/5
in equation 1
x = (5у + 4)/2
x = (5*-44/5 + 4)/2
x = (-44+4)/2
x = -40/2
x = -20
