Question

Show all work to solve 1 over x plus 3 over 8=1 over 2. Use complete sentences to explain how to solve this equation.

Answer 1

1/(x + (3/8)) = 1/2 is the question?

Answer 2

\[\LARGE \frac1x +\frac38 =\frac12\]

Answer 3

KRESHNIK IS RIGHT

Answer 4

redshift I'll leave it to you :)

Answer 5

1/x + 3/8 = 1/2

So we need to make a common denominator so that we can do fraction addition:
We can do this by multiplying each numerator by the other denominator and adding them to make the numerator, and multiply each denominator together to get the common demominator:
( 1(8) + 3(x) )/(8x) = 1/2

then we can cross-multiply:
(8 + 3x)(2) = 8x

then we expand:
16 + 6x = 8x

then we subtract 6x from each side:
16 = 2x

then we divide both sides by 2:
8 = x

I always hated explaining math in school lol

Answer 6

\[\LARGE \frac1x=\frac12 -\frac38\] LOL I was somewhere else, when I got back I saw that you were typing ... I thought about doing it ... :P

Answer 7

I hate my online class :P

Answer 8

Actually you could do it Kreshnik's way much easier.

1/x = 1/2 - 3/8

Common denominator by multiplying 1 and 2 in 1/2 by 4:
1/x = 4/8 - 3/8
1/x = 1/8

x=9

Answer 9

x = 8! i mean

Answer 10

well I don't hate math at all , just because I don't know it, I think people should try harder and not just to say, ahh I hate this ! LOL

Answer 11

Truee ...:P

Answer 12

THANKS BTW
