Where do the lines 5x 3y 20 and 2x - y -14 intersect?
By Simultaneous Equations. Assuming you mean 5x + 3y + 20 = 0 2x - y - 14 = 0. We will eliminate 'y' by multiplying the bottom eq'n by '3' and then adding. Hence 5x + 3y + 20 = 0 6x - 3y -42 = 0 Add 11x -22 = 0 11x = 22 x = 22/11 x = 2 when x= 2 2(2) - y - 14 =0 4 - y - 14 = 0 -y - 10 = 0 y = -10 So the point of intersection in ( x.y.) form is ( 2, -10).
