The solution is (-4,3) -3x-3y=3 y=-5x-17 so find the y in the first equation in terms of x -3x-3y=3 -3y=3x+3 y=-x-1 then set the two equations equal to each other y=-x-1 y=-5x-17 -x-1=-5x-17 4x=-16 x=-4 now put the x into one of the equations -3(-4)-3(y)=3 12-3y=3 -3y=-9 y=3 so the solution is (-4,3) to check it, put the points into equations and see if they're correct -3(-4)-3(3)=3 12-9=3 3=3 correct
