answer these question

Answer 1

Hope it will help you

Answer 2

5x + 2y = 3 ......(1)
x + 5y = 4 ......(2)
now multiply 2 equation by 5 we get...
5x + 25y = 20 .....(3)
now subtract 1 equation from 3 equation
5x + 25y = 20
- 5x + 2y = 3
_____________
23y = 17
y = 17/23
now put the value of y in 2 equation we get..
x + 5×17/23 = 4
x = 4 - 85/23
x = (92 - 85)/23
x = 7/23
:. x = 7/23 & y = 17/23
