Answer:
Step-by-step explanation:
x + 2y = 16 _______(1)
x - y = -2_______(2)
(1) - (2)
[tex]x + 2y - (x - y) = 16 - ( - 2) \\ x + 2y - x + y = 16 + 2 \\ 2y + y = 18 \\ 3y = 18 \\ y = \frac{18}{3} \\ y = 6 \\ [/tex]
y = 6,
[tex]x + 2y = 16 \\ x + 2(6) = 16 \\ x + 12 = 16 \\ x = 16 - 12 \\ x = 4 \\ [/tex]
