You can put this solution on YOUR website!

f%28x%29=%284x%2B7%29%2F%287x-4%29
g%28x%29=8x%2F%287x-4%29
a.) do you have %28f%2Bg%29%2Fx; it is %28f%2Bg%29%28x%29%2Fx
or you have %28f%2Bg%29%28x%29<- I guess you have this
%28f%2Bg%29%28x%29=%284x%2B7%29%2F%287x-4%29%2B8x%2F%287x-4%29......denominators are same, so we have
%28f%2Bg%29%28x%29=%284x%2B7%2B8x%29%2F%287x-4%29
%28f%2Bg%29%28x%29=%2812x%2B7%29%2F%287x-4%29
