Last question solved by elimination:
20x-4+3y+9=120
20x+3y=115
3x+3-2x+2y=18
x+2y=15
20x+3y=115
x+2y=15
40x+6y=230
3x+6y=45
37x=185
X=5
5+2y=15
2y=10
Y=5
So answer A with X=5 y=5
But the answers make no sene to me. Either I did something really wrong or they hoping other people do something really wrong.
