@helpme375 please note that your expression can berewritten as follows: $\frac{{x + 3}}{{6\left( {5x - 7} \right)}} \cdot \frac{{8\left( {5x - 7} \right)}}{8}$

try cross multiply

irish was typing so i thought he is going to help you.

14. Michele_Laino

I think that answer is: $\frac{{x + 3}}{6}$

how did you get it

16. Michele_Laino

when you simplify that expression above, then factors 5x-7 cancel, also factors 8 cancel, so we reamin with (x+3) as numerator and 6 as denominator

17. Michele_Laino

remain*

18. anonymous

but would you be left with (x+3)/8 after you take away 5x-7

19. Michele_Laino

here is the right simplification: |dw:1443971900756:dw|
