Answer 2

Answer:

x = 5 and y = -4

Step-by-step explanation:

x/3 + 2y/3 = -1 .......(1)

=> x+2y/3 = -1

=> x+2y = -3

=> x = -3 - 2y .........(2)

x - y/3 = 3 ..........(3)

substituting the value of x in equation 3, we get,

-3 - 2y - y/3 = 3

=> -3 - 3y = 3*3

=> -3(1 + y) = 9

=> 1 + y = 9/-3

=> 1 + y = -3

=> y = -3-1

=> y = -4 (ans)

putting the value of y in equation 2, we get,

x = -3 - 2(-4)

=> x = -3 + 8

=> x = 5 (ans)
