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(1) – 7(36) =-254 X
4(1) – (36) =-32 X

x = 41

y = 24

Step-by-step explanation:

Systems of equations is,

-2x - 7y = -250 (1)

4x - y = 140 (2)

Equation (1) multiplied by 2 then added to equation (2)

 -4x -14y = -500

(+)   4x - y = 140  

         -15y = -360

            y =

           y = 24

by putting y = 24 in equation (2),

4x - 24 = 140

4x = 140 + 24

x =

x = 41

For x = 41 and y = 24 both the equations are true.

Equation (1),   -2(41) - 7(24) = -250  [True]

Equation (2),   4(41) - (24) = 140  [True]
