A 12ft. board is cut into two pieces so that one piece is 8 ft. longer than 3 times the shorter piece. If the shorter piece is x feet long, find the lengths of both pieces

x feet = short piece.

12-x = long piece.

3x+8 = 12-x

Solve for x.

x + (8 + 3x) = 12

4x + 8 = 12

4x + 8 - 8 = 12 - 8

4x = 4

x = 1

One piece is 1 foot long

The other piece is 11 feet long

Does that make sense?

(3 * 1) + 8 = 11
