The answer for this problem is 120√6
7 pounds = 16 pounds and 1 pound = 6 pounds and 16 ounces.
(6 pounds + 16 ounces) minus (5 pounds + 10 ounces) = 1 pound + 6 ounces
Something like 4//1/255 ?
just multiply The number you started with be the denominator of the fraction.
4 * 255 = 1020
The reason why is that though I didn't say so you are actually multiply both top and bottom by 255
4 * 255
==
1 * 255
--
255
The bottom 255s cancel. and you are left with 4 * 255 on the top.
Short cut you want. Short cut you get.

For easy calculation first transpose the equation into the y-intercept form then create your table and plot the graph.
If 2x - 6y = 12
then -6y = 12 - 2x
6y = 2x - 12
y = [2 (x - 6)] /6
⇒
y = (x - 6) / 3
The table and graph are attached below.
