Question 1043754
First step is wrong.


------------------------------------
Question # 1043749,
Solve for x. 
(a + x) / b - (c - x) / d = a / b 
lcd = bd 
(a + x)* bd - (c - x) * db = abd 
How do I proceed ? 
Non-homework. 
-----------------------------------


First step is
{{{bd((a+x)/b-(c-x)/d)=bd(a/b)}}}


Second step is
{{{d(a+x)-b(c-x)=da}}}


Now continue.
Continue.
{{{highlight(x=(cb)/(b+d))}}}
