Answer:
y=8
Step-by-step explanation:
First you have to solve for x.
so you take both of the equations that have x in it and equal them to each other:
(8x-31)=(6x+3)
that gives you
x=17
then all you have to do it take 17, and input it to one of the equations that haver x in it, then solve that and add that number to 5y+35 and equal it to 180.
6(17)+3=105
105+(5y+35)=180
y=8
So you got the right answer!
