Answer: X=1 Y=-5
Explanation:
−9x+2y+−2y=−19+−2y(Add -2y to both sides)
−9x=−2y−19 (Divide by 9 on both sides)
x= 2/9y+19/9 now Substitute 5(2/9y+19/9)+4y=-15=
46/9+95/9=-15 (simplify both sides)
46/9+95/9+-95/9=-15+-95/9 (Add (-95)/9 to both sides) =
46/9y=-230/9 (now divide both sides by 46/9) than equals
y=-5
for X we plug in -5 like this: X=2/9(-5)+19/9 now just evaluate than simplify both sides which equals: 1
