Answer:
One piece is
inches and another piece is
inches
Step-by-step explanation:
Let smaller piece length be 
Let larger piece length be 
Since total of two pieces is 43, we can write:

Also, one piece is twice as long as the other (so longer piece is definitely twice as the short piece), we can write:

<em>Substituting equation 2 into equation one, we can solve for s:</em>

<em>Thus longer piece is:</em>

in the like term you can add directly and make it single fraction and in unlike term you have to take LCM of denominator .
Just subtract the number infront of missing number to the opposing number
I think this is the answer, sorry I am not 100% sure
