Substitute y=x-8 into the first equation

2x+3(x-8)=1

Expand

2x+3x-24=1

Collect like terms

5x-24=1

Move negative 24 to the other side as a positive number

5x= 25

Divide both sides by 5

25/5 is 5

Therefore x is equal to 5

Sub x equal five in second equation

y=5-8

5-8= -3

Therefore, y is equal to -3


Therefore, x is equal to 5 and y is equal to -3
