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?
