प्रश्न
Find x, y if `[(-2,0),(3,1)][(-1),(2x)] + 3[(-2),(1)] = 2[(y),(3)]`
उत्तर
`[(-2,0),(3,1)][(-1),(2x)] + 3[(-2),(1)] = [(y),(3)]`
`=> [(-2xx (-1) + 0 xx 2x),(3xx(-1)+ 1 xx 2x)] + [(-6),(3)] = [(2y),(6)]`
`=> [(2),(-3+2x)] + [(-6),(3)] = [(2y),(6)]`
`=> [(-4),(2x)] = [(2y),(6)]`
`=> -4 = 2y and 2x = 6`
`=> y = -2 and x = 3`
