Answer 1

Answer:

answer check plz mark brialint answer

Answer 2

Answer:

1.x=0 y=2

2.x=0 y=5

Step-by-step explanation:

bro when we have two variable we can take any number in that place

in first one we have 2x-y=2

na so lets take 0 in the place of x

then 2×0-y=2

0-y=2

y=2 got it

we can take like that in the place of y also

2x-y=2

2x-0=2

×=2/2

x=1

got it

in second one x+3y=15

×=0

0+3y=15

y=15/3

y=5

so u can re check also by subtittuting it in that place
