Solve: x/6+x/5=7/6


%0D%0Ax%2F6%2Bx%2F5=7%2F6%0D%0A 

The common denominator is 30, so we rewrite everything so that they can be added. 

%0D%0A%28x%2F6%29%285%2F5%29%2B%28x%2F5%29%286%2F6%29=%287%2F6%29%285%2F5%29%0D%0A 





%285x%2B6x%29%2F30=35%2F30%0D%0A 


If we multiply both sides of the equation by 30 then simplify we get the following 

11x=35 

Finally after we divide by 11 we know the value of x 
x=35%2F11
