2х + Зу = 8
у = 2х + 8

x = -2, and y = 4

Step-by-step explanation:

In order to solve for x, we need to plug in y.

2x + 3y = 8

2x + 3(2x+8) = 8 --> distribute the 3 to (2x+8)

2x + 6x + 24 = 8 --> add 2x and 6x

8x + 24 = 8 --> subtract 24

8x = -16, and you'd get x = -2

Now solve for y with x:

y = 2x+ 8

y = 2(-2) + 8 --> simplify by multiplying 2 and -2

y = -4 + 8 --> basically 8 - 4

y = 4

Check your

Plug in the numbers:

2x + 3y = 8

2(-2) + 3(4) = 8 --> -4 + 12 = 8 --> 8 = 8

y = 2x + 8

(4) = 2(-2) + 8 --> 4 = -4 + 8 --> 4 = 4

Hope this helps! :)

this doesn't make sense lol

goog may be able to you find that answer
