Question

Where to Dig: The dinosaur's

tail bones are at the solution
point to the system of
equations below.
- 2x - 7y = -250
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

Answer 1

Answer:it’s 41 and 24

Explanation:

Answer 2

x = 41

y = 24

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 =
`(360)/(15)`

y = 24

by putting y = 24 in equation (2),

4x - 24 = 140

4x = 140 + 24

x =
`(164)/(4)`

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]
