How do I solve 4/e-3=5

Question

Please help. How do I solve 4/e-3=5

Answer 1

4/e - 3 = 5

e=1/2

4/(1/2) -3 = 5

4(2) -3 = 5

8-3 = 5

5=5

that's how the problem is written, but maybe you really meant to write it as

4/(e-3) =5

then e-3= 4/5

and

e = 4/5 +3= 3.8

e=3.8

this is somewhat strange though, as "e" in mathematics is a constant, an irrational number = about 2.1828....

then 4/e-3 =5 is a contradiction, never true. That's whether you treat it as 4/(e-3)=5 or as (4/e)-3 =5.

math usually uses letters at the end of the alphabet for variables, such as x, y or z. letters nearer the top of the alphabet are used for constants, a, b, c, e, k, l, m

so, it's unclear what the problem really is. Is it possible you may have miscopied the problem? Or maybe whoever gave you this problem mis-copied it? a typo somewhere?
