Let x= the length of the Piece of wood
The first piece of rope, we are told,=3x-2
The second piece of rope, we are told,=3x+15
AND WE ARE TOLD THAT THE FIRST PIECE OF ROPE IS THE SAME LENGTH AS THE SECOND PIECE OF ROPE. THERE'S SOMETHING WRONG WITH YOUR PROBLEM. 3X-2 CANNOT EQUAL 3X+15.
CHECK THE WORDING OF YOUR PROBLEM.
