Question 1199376: b=p-2l/2 is the same as b=p/2-l
l=2s-an/n is the same as l=2s/n-a
d=c-16e/16 is the same as d=c/16-e
x=my-r/m is the same as x=y-r/m
these are the answers of my textbook (equations) when solving subject of the formula and as you can see there are 2 solutions that can be taken as correct . But , how are they both the same? could you explain the logic behind this ? Thanks in advance. Answer by math_tutor2020(3817) (Show Source):
You can put this solution on YOUR website!
You mentioned
"b=p-2l/2 is the same as b=p/2-l"
which I'm assuming you are saying is the same as
This claim is true because of these steps
Break up the fraction
The '2's cancel for the second fraction.
Similar cancellations occur for the other equations.
Eg:
To go from to , the 'n's cancel in the 2nd fraction.
To go from to , the '16's cancel in the 2nd fraction.

Side note:
when wanting to divide all of something like p-2L over 2, then you should use parenthesis.
You should say (p-2L)/2 instead of p-2L/2
