Question

x- y = 5
2 x + 3y = 10​

Answer 1

{x - y = 5 x = 5 + y

{2x + 3y = 10

2(5 + y) + 3y = 10

10 + 2y + 3y = 10

2y + 3y = 0

5y = 0

y = 0/5

y = 0

x = 5 + 0

x = 5

S = {(x , y) = (5 , 0)}

Answer 2

_____________________

x - y = 5

2x + 3y = 10

(3x - 3y = 15)

2x + 3x - 3y + 3y = 15 + 10

5x = 25

x = 25/5

x = 5

_____________________

x - y = 5

5 - y = 5

y = 5 - 5

y = 0

_____________________

S = { 5 : 0 }
