Solution of y=2x-1 and y=-x-5

Solution of y=2x-1 and y=-x-5
You can set the two equations equal to one another since they both equal y.2x-1 = -x-5And then solve for x.2x +x = -43x = -4x = -4/3Now substitute x into either one of the original equations to get y.y = 2(-4/3) -1y = -3 2/3Alternatively, you can graph the two equations on a graphing calculator and find the intersection.Y1 = 2x-1Y2 = -x-5The intersection is (-1.333, -3.666) which is the same as (-1 1/3, -3 2/3) ...
