Solution:

Note that:

  • y = -x + 16
  • 30 = 2x + y

Substitute the value of y into the equation to find x.

  • 30 = 2x + y
  • => 30 = 2x - x + 16
  • => 30 = x + 16
  • => 30 - 16 = x
  • => x = 14

Substitute the value of x into any equation to obtain the value of y.

  • 30 = 2x + y
  • => 30 = 2(14) + y
  • => 30 = 28 + y
  • => 30 - 28 = y
  • => y = 2

Putting the values in (x,y) form.

  • (x,y) ⇒ (x = 14,y = 2) ⇒ (14,2)
