Ok, first you know you have 2 pieces of boarder.
let x= the shorter piece
let x+5= the longer piece (only logical because it is 5ft longer)
set up your equation like this.
x+x+5=105
2x+5=105 (you can add the x's together)
2x+5-5=105-5 (you must get like terms together)
2x=100 (divide both sides by 2)
x=50
x+5=55
the shorter piece is 50ft and the longer piece is x+5 so it is 55ft.
hope this helps
