`A={:[(1,2),(3,4),(5,6)]:},B={:[(0,1),(-1,2),(-2,1)]:}`, then find matrix X such that 2A +3X=5B.

Text Solution

Verified by Experts

We have, 2A+3X=5B
3X=5B-2A
`=5{:[(0,1),(-1,2),(-2,1)]:}-2{:[(1,2),(3,4),(5,6)]:}`
`={:[(-2,1),(-11,2),(20,-7)]:}`
`X=(1)/(3){:[(-2,1),(-11,2),(-20,-7)]:}`
`={:[(-(2)/(3),(1)/(3)),(-(11)/(3),(2)/(3)),((-20)/(3),-(7)/(3))]:}`
