Answer:
x = 2, y = -1
Step-by-step explanation:
Now change the equation,
→ x + y = 1
→ y = 1 - x
Then the value of x will be,
→ 2x + y = 3
→ 2x + 1 - x = 3
→ x = 3 - 1
→ [ x = 2 ] 
Therefore, the value of x is 2. 
Now value of y will be,
→ y = 1 - x
→ y = 1 - 2
→ [ y = -1 ] 
Hence, the value of y is -1.
