This is a conversion from one American standard unit to another, NOT from American standard to metric.
"Multiply to change larger units to small units." is a valid rule only if you use specific conversion factors.
The best way to change units is to use Dimensional Analysis...

14x-2>2(6x-8)
14x-2>12x-16
2x>-14
x>-7

No. We have the Constitution, laws passed by Congress and Regulations written by a myriad of Executive organizations such as the FCC, ICC, FDA and many others. There are bound to be conflicts within such a huge body of laws. Then there is a similar
set of State groups that create...

the sample solution is not a solution.
x+2y-z=3 using the sample solution
2+6-0=?3
8≠3
Thus the sample solution is not a solution.
A set of three independent equations can be solved for three variables. In this case the...

This is scientific notation: A number multiplied by ten to a power. Moreover, It is Standard Scientific Notation: the number in front is > or = to 1 and <10

Don't get confused by the fact that a is negative and c=0. This is standard factoring.
ax^2+bx+c = (ax+b)(x) Remember: c=0

If someone tells you that the answer is x=5/2 then they should be able to show you how to get that answer. My answer is different.
(x-2)/3 + (x-2)/4 = 7/24 I approach this by expressing everything as 24ths. Thus I must multiply the first term by 8/8 and the second term...
