Answer:

x = -1 and y = 1

Step-by-step 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

<u>y = 1</u>

Placing the value of y in eq. (i)

5x + 2(1) = -3

5x + 2 = -3

5x = - 5

<u>x = -1</u>
