Answer:
(6, -1)
Step-by-step explanation:
Replace the x in the first equation with 5 - y since x is equal to it:
5 - y - 2y = 8 subtract like terms
5 - 3y = 8 subtract 5 from both sides
-3y = 3 divide both sides by -1 to simplify and make the y positive
y = -1
now since we know the value of y we can use it to find x
x = 5 - y
x = 5 - (-1) (two - = +)
x = 6
