  (x, y) = (4, 1)

Step-by-step explanation:

We assume you want to solve ...

Multiply the first equation by 3 and add the second:

  3(x +y) +(5x -3y) = 3(5) +(17)

  8x = 32 . . . . . . simplify

  x = 4 . . . . . . . . .divide by 8

  4 +y = 5 . . . . . . substitute into the first equation

  y = 1 . . . . . . . . .subtract 4

The solution is (x, y) = (4, 1).
