# Given (2, 1),(-3, 4) X = (7),(6) Write the Matrix X - Mathematics

Sum

Given [(2, 1),(-3, 4)] x = [(7),(6)] Write the matrix x

#### Solution

Let x = [(x),(y)]

:. [(2, 1),(-3, 4)] xx [(x),(y)] = [(7),(6)] => [(2x + y),(-3x + 4y)] = [(7),(6)]

=> 2x + y = 7 and -3x + 4y = 6

On soling the above simultaneous equation in x and y, we have x = 2 and y = 3

:. The matruix x = [(x), (y)] = [(2),(3)]
