anonymous · Answer

so like how do i do that like im confused

solomonzelman · Answer

x       +      y    =    3
2x     –       y    =    6
----------------
3x     +     0y    =   9

good ?

o ok

anonymous · Answer

so like what else do I do @SolomonZelman

@satellite73

anonymous · Answer

actually wouldn't it be 2x$$^{2}$$ + 0 =9

anonymous · Answer

that's what I thought @danirubi

anonymous · Answer

wait so would it be 2x^2=9 and like im not sure what else I have to do

anonymous · Answer

well I'm not sure it's 100% correct but I did my best
2(2.25 x 2.25)=9
2(4.5)=9
9=9
x=2.25
hope that makes sense
