Question 1112450
 A board 25 feet long is cut into two pieces.
L + s = 25
s = -L + 25
 Five feet less than two times the length of the longer piece is equal to three times the length of the shorter piece.
2L-5 = 3s
replace s with (-L+25)
2L - 5 = 3(-L+ 25)
2l = -3L + 75 + 5
2L + 3L = 80
5L = 80
L = 80/5
L = 16
find s
 s = -16 + 25
 s = 9
 Find the length of each piece.
Longer = 16, shorter = 9

"Five feet less than two times the length of the longer piece is equal to three times the length of the shorter piece.
2(16) - 5 = 3(9)
32 - 5 = 27
