Question

A board 22 cm long is cut into two pieces. One piece is 4 cm longer than twice the length of the other piece. Find the length of each piece

Answer 1

22 - x = 2x + 4

18 = 3x

6 = x, which is the shorter piece.

22 - x is the longer piece, and since we have x, just plug in for x.

22 - 6 = 16.
