    i would multiply the first equations by \(2\) and the second equation by \(3\) that would give \[10x-18y=-32\]\[6x+18y=-48\] then i would add the two equations together to get \[16x=-80\] divide by \(16\) to get \(x=-5\)

    now that you know \(x=-5\) you can substitute \(-5\) for \(x\) in either equation and solve for \(y\)

    \[2(-5)+6y=-16\]\[-10+6y=-16\]\[6y=-6\]\[y=-1\]
