Best ResponseYou've already chosen the best response.0Use elimination and find the answer first. All the methods should give the same answer, right?

Best ResponseYou've already chosen the best response.0You said you know how to use elimination. Try multiplying the first equation by $$2$$ and add it to the second equation...

Best ResponseYou've already chosen the best response.1\[3x9y=3 [1]\] \[6x  3y= 24 [2]\] \[2\times [1]\] \[6x18y=6 [3]\] \[[2][3]\] \[(6x  3y)  (6x18y)= (24)(6)\]

Best 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.
