Question

Can somebody solve using elimination
-x+y=4
-2x+y=2

Answer 1

Answer:

Step-by-step explanation:

subtract them

-x=-2

x= 2

substitute x value in any equation

-2 + y = 4

y= 4+2

y=6

Answer 2

Answer:

ny doing 1 × 2 - 2

-2x + 2y = 8

- 2x + y = 2

= 3y = 6

y = 2

putting the value of y in equation 1 we get

-x + y = 4

-x +2 = 4

.: x = -2
