Answer 1

`2X + 3Y = [(2,-2),(-1,5)]` ...(3)

`3X + 2Y = [(2,-2),(-1, 5)]` ....(4)

Multiplying equation (3) with (2), we get:

`2(2X + 3Y) = 2[(2,3),(4,0)]`

`=> 4X + 6Y = [(4,6),(8,0)]`   ....(5)

Multiplying equation (4) with (3), we get:

`3(3X + 2Y) = 3[(2,-2),(-1,5)]`

`=>9X + 6Y = [(6,-6),(-3, 15)]` ....(6)

From (5) and (6), we have:
