Question

A 18 inch string is cut into two where the second piece is 3 inches longer than twice the first.

Answer 1

It is given in the question that,

A 18 inch string is cut into two where the second piece is 3 inches longer than twice the first.

Let the length of the first piece be x inch.

So length of second piece is

$(2x+3)inch$

And total length is 18 inch. That is

$x+2x+3 =18 \\ 3x+3 = 18 \\ 3x = 15 \\ x =5$

So the length of the first piece is 5 inch and the length of second piece is

$(2*5 +3) = 13 inches$
