In each of the fowllowing cases, find a and b
(i) `(2a+b,a-b)=(8,3)`
(ii) `((a)/(4),a-2b)=(0,6+b)`

Explanation

To solve the given problems step by step, we will break down each part of the question.

### Part (i): Solve `(2a + b, a - b) = (8, 3)`

1. **Set up the equations**: From the given ordered pairs, we can set up two equations:
- \( 2a + b = 8 \) (Equation 1)
- \( a - b = 3 \) (Equation 2)
