Answer 1

Answer:

2x-5y=10 and 4x-y=20 then (x-y)

Answer 2

Step-by-step explanation:

2x-5y=10

(4x-y=20)×5

20x- 5y=100

2x-5y=10 -20x+5y=100

-18x+0= -90

18x=90

x= 90/18

x= 5

2x-5y=10

2×5-5y=10

10-5y=10

-5y = 10-10

-5y =0

y= 0/-5

y= 0

then (x-y) ....

(5-0)

5 ......

this is a answer .......
