Answer:

([tex]\frac{31}{4} , \frac{-1}{8}[/tex])

Step-by-step explanation:

use substitution:

3x+2y=23

x=2y+8

plug in 2y+8 for x

3(2y+8)+2y=23

distribute:

6y+24+2y=23

combine like terms:

8y+24=23

solve the equation:

y=-1/8

substitute -1/8 for y:

x=2(-1/8)+8

solve the equation:

x=31/4
