The dinosaur's tail bones are at the solution point to the system of equations below. –2x – 7y = –250 4x – y = 140 every time you click a point using the cps, the equations below will update. remember, the solution is the point that makes both equations true. –2( 0 ) – 7( 20 ) = -148 x 4( 0 ) – ( 20 ) = -4 x
