Question

what does x+3 over 4 - x-4 over 2 = 3 over 8
i got -19 over 2

Answer 1

well but each fraction over a denominator of 8

\[\frac{2(x + 3)}{8} - \frac{4(x - 4)}{8} = \frac{3}{8}\]

so you are really solving

2(x + 3) - 4( x - 4) = 3

distribute, collect like terms and then solve for x

Answer 2

so it is a positive 19 over 2?

Answer 3

so its - 2x + 22 = 3
- 2x = -19

x = 19/2

yep... thats the answer... well done
