Estimate the solution to the following system of equations by graphing.

-2x+2y=2
-3x+6y=5

A.(-1/4,2/3)
B.(-2/3,1/3)
C.(-1/3,2/3)
D.(-1/3,1/2)

Respuesta :

(-2x+2y=2)* (-3) 
-3x+6y=5

        6x-6y=-6
 +    -3x+6y=5
       3x       = -1
         x= -1/3

(-2x+2y=2)/2    ------->   -x+y = 1 ------->  y = 1+x

y=1 - 1/3 = 2/3
y = 2/3

Answer : C.(-1/3,2/3).
