Problema Solution
An electrician cuts a 136 ft long piece of cable. One piece is 16 feet less than 3 times the length of the other piece. Find the length of each piece.
Answer provided by our tutors
We assume the 136 ft long cable is cut into 2 pieces.
Let 'x' the length of the first piece and 'y' the length of the second piece.
y = 3x - 16
x + y = 136

x = 38 ft
y = 98 ft
The lengths of the pieces are 37 ft and 98 ft.
