#### Question

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)]`

Is there an error in this question or solution?
