Answer 1

Answer:

I will do it tomorrow morning please forgive me

Answer 2

Explanation:

( x-y, 2x+y )=(5,3)

x-y = 5 |. 2x+y= 3

x=5+y

Substitute the equation x=5+y in 2x+y= 3

2x+y= 3

2(5+y) + y = 3

10+2y +y = 3

10 + 3y = 3

3y = 3- 10

3y = -7

y= -7/3

substitute obtained y value in 2x+y= 3 or x-y = 5

x - (-7/3) = 5

x + 7/3 = 5

x= 5 - 7/3

x = 8/3
