It's a system, I have to solve them but I can't figure out how to do it.

you can solve using elimination: multiply the first equation by 2 to eliminate the x's:\[~~~~~2~(3x9y=3)~~~~~~\implies~~~~~~~~6x18y=6\]\[\underline{~(6x3y=24)}~~~~~\implies~~\underline{(6x3y=24)}\]\[~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~015y=30\]now solve for y:\[15y=30\]divide by 15:\[y=2\] knowing the value of y we could now use substitution to solve for x: pick either of the two equations and plug in the value of y\[3x9(2)=3\]distribute:\[3x+18=3\]subtract 18:\[3x=15\]divide by 3:\[x=5\] so: \(x=5\) and \(y=2\) hope this helps! :)
