Find x and y from the given equations:
`[(-8, x)] + [(y, -2)] = [(-3, 2)]`
Advertisements
उत्तर
`[(-8, x)] + [(y, -2)] = [(-3, 2)]`
`=> [(-8 + y, x - 2)] = [(-3, 2)]`
Equation the corresponding elements, we get
–8 + y = –3 `=>` y = –3 + 8 = 5
And x – 2 = 2 `=>` x = 2 + 2 = 4
Thus, we get, x = 4 and y = 5.
