B. 9A^2 - 16B^2
If you need me to explain. I will.
X=2W+1-1/Y
YOU SUBTRACT 2/Y TO START TO GET X ALONE.
WHICH WOULD MAKE IT 2X=4W+2-2/Y.
THEN YOU MUST DIVIDE BOTH SIDE BY TO FINISH GETTING X ALONE WHICH WOULD GIVE YOU YOUR ANSWER
340 = (2 × length) + 160.
Subtract 160 from both sides.
180 = 2 × length
Divide both sides by 2.
90 = length.
