Answer 2

Answer:

Step-by-step explanation:

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

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

x = 1 - 3y ------------(3)

substituting equation (3) in (1)

2(1-3y) + y = 3

2 - 6y + y = 3

-5y = 3-2

-5y = 1

y = -1/5

substituting y value in equation (3)

x = 1 - 3 x -1/5

x = 1 + 3/5

x = 5 + 3/5

x = 8/5
