Answer:
x= -10, y= 1
Step-by-step explanation:
-x -8y= 2 -----(1)
x -5y= -15 -----(2)
From (2):
x= 5y -15 -----(3)
Substitute (3) into (1):
-(5y -15) -8y= 2
Expand:
-5y +15 -8y= 2
-13y +15= 2
13y= 15 -2
13y= 13
Divide both sides by 13:
y= 13 ÷13
y= 1
Substitute y= 1 into (3):
x= 5(1) -15
x= 5 -15
x= -10
