# If 3 a − B = 5 0 1 1 and B = 4 3 2 5 , Then Find the Martix A. - Mathematics

Sum

If 3"A" - "B" = [(5,0),(1,1)] and "B" = [(4,3),(2,5)], then find the martix A.

#### Solution

3"A" - "B" = [(5,0),(1,1)]

We need to calculate A.

3"A" = [(5,0),(1,1)] + "B"

"B" = [(4,3),(2,5)]

3"A" = [(9,3),(3,6)]

"A" = (1)/(3) [(9,3),(3,6)]

"A" = [(3,1),(1,2)]
