2x + y = 5
x + y = 5/2
3x + 2y = 8
x + 2y = 8/3
x + y = 8/3 × 2
x + y = 8/6
x + y = 4/ 3

Answer:
Here we have, 2x + y = 5 → (1)
3x + 2y = 8 → (2)
Let Multiply, equation (1) by 2
So, 4x + 2y = 10 → (3)
Subtracting equation (3) - (2)
4x + 2y - [3x + 2y ] = 10 - 8
4x + 2y - 3x - 2y = 2
x = 2
In the equation (1), put x = 2
2 × 2 + y = 5
4 + y = 5
y = 5 - 4
y = 1
