Answer:   x = 3, y = 1 OR  (3, 1)

Step-by-step explanation:

let 2x + 3y = 9  be [a]   &   y = x − 2 be [b]

First, lets substitute [b] into [a] and solve for x

   2x + 3( x - 2) = 9

          2x + 3x  = 9 + 6

                   5x = 15

                      x = 3

Now, since x = 3, we can substitute for x in [b]

       ⇒  y = 3 - 2

             y = 1

∴ the solution for the system of equations is x = 3, y = 1 OR  (3, 1)
