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

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

    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

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