Where to Dig: 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( x ) - 7(y) = 250 X

4(x ) - (y) = 140 X
