2x + 3y = 7 3x + 2y = 8

Answer:

$\boxed{\sf \ \ \ x=2, \ \ y =1 \ \ \ }$

Step-by-step explanation:

Hello,

Pls post the full question next time so that we can make sure what is expected.

I assume that you want to solve for (x,y)

(1) 2x + 3y = 7

(2) 3x + 2y = 8

2*(2)-3*(1) gives

2*3x + 2*2y - 3*2x - 3*3y = 2*8 - 3*7 = 16 - 21 = -5

6x - 6x + 4y -9y = -5

-5y=-5

y = 1

and we can replace in (1)

2x + 3*1 = 7

2x = 7 - 3 = 4

x = 2

hope this helps
