Answer:

The solution is (3,2)

Step-by-step explanation:

x - y = 1 →equation 1

-x + 3y = 3 →equation 2

by elimination method,

x - y = 1

-x + 3y = 3

-----------------

0 + 2y = 4

2y = 4

y = 4/2

y = 2

substitute y=2 in equation 1

x - y = 1

x - 2 = 1

x = 1 + 2

x = 3  

∴(3,2) is the solution
