Answer 2

x = -1 and y = 1

Explanation:

5x + 2y = -3 . . . . . . . (i)

x + 5y = 4 . . . . . . . (ii)

• Finding x in terms of y from eq. (ii) :-

x + 5y = 4

x = 4 - 5y

• Placing this value of x in eq. (i) :-

5(4 - 5y) + 2y = -3

20 - 25y + 2y = -3

-23y = - 23

y = 1

• Placing the value of y in eq. (i)

5x + 2(1) = -3

5x + 2 = -3

5x = - 5

x = -1
