Answer: y = 8 , x = 4

Explanation:

gosh darn i haven done this since algebra 1 !!

since both equations equal y, we can make them equal to each other since y = y

-2x +16 = 2x (im just gonna simplify without all the extra steps sorry)

x = 4 (this is the first answer)

now we can plug in x to find y

y = 2(4)

y = 8 (second answer)

im sorry if the grammar is horrid its 3 am
