Answer: the original length of the piece of wood is 23 feet
Step-by-step explanation:
Let x represent the original length of the piece of wood.
He cuts 3 feet off the piece of wood. This means that the remaining length of wood would be
(x - 3) feet
he cuts the remaining length of wood into four equal parts. if each part is 5 feet long, it means that
(x - 3)/4 = 5
Cross multiplying by 4, it becomes
x - 3 = 4 × 5
x - 3 = 20
x = 23
