Step-by-step explanation:
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
