Question

Find x and y from the given equations:

`[(-8, x)] + [(y, -2)] = [(-3, 2)]`

Sum

Solution

`[(-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.
