The answer is x=22 because you just have to add the two equations together and then solve for 8x+4=180

Answer:
I think the output can be any numbers because you don't have the function to put -8 in, so I can't identify the output exactly is.
Step-by-step explanation:
X+y=8
multiply the first equation by 3 to get rid of x
3x+3y=24
3x+2y=14
subtract equation 1 from 2
y=10
substitute to find the value of x
x+10=8
x=-2
