I still need help with this!

anonymous · Answer

what do u think the answer is ?

anonymous · Answer

hint solve simultaneously

anonymous · Answer

D. there is no solution if not then A. (18, 9)

anonymous · Answer

yes u are right its D because

anonymous · Answer

2x + 2y = 18
 x + y = 9

solving simultaneously 
1(2x+2y=18)
2(x+y=9)

2x+2y=18
2x+2y=18
 
you cant eliminate one of those letters, and while keeping the 
other letter (either x or y)
