Use elimination and find the answer first. All the methods should give the same answer, right?

You said you know how to use elimination. Try multiplying the first equation by $$2$$ and add it to the second equation...

$$ (3x9y=3) (2)$$ 6x  3y= 24

\[3x9y=3 [1]\] \[6x  3y= 24 [2]\] \[2\times [1]\] \[6x18y=6 [3]\] \[[2][3]\] \[(6x  3y)  (6x18y)= (24)(6)\]

Azteck Group TitleBest ResponseYou've already chosen the best response.1
\[3y+18y=30\] The x's cancel out. Now you can solve for y. Once you solve for y, you can then substitute the y component that you just found, into any one of the equations above to find your xvalue.
