abb0t · Answer

Use substitution. The simplest one would substitute for x.

anonymous · Answer

im bad at substitution ims orry :(

abb0t · Answer

That means, subtract 3y from zero. Plug in -3y for x on the first equation. And then use algebra to solve for Y
once you have your y, plug it back in to equation y = -3x
and solve for x.

whpalmer4 · Answer

You could also use elimination — subtract the second equation from the first, and the y terms will drop out and leave you an equation for x.  Solve that, then plug the value into either equation to find y.
