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 ?

Here is how to begin:
You identified correctly the lowest common denominator. Multiply the members by this common denominator (which will use Multiplication Property of Equality). You began that. You also made a mistakes in the both members.
What should be next? Distributive Property!
The rest should be straightforward and not at all complicated.

It makes no sense for you to proceed because you're incorrect ------- Multiplying by LCD, bd
ad + dx - bc + bx = ad
dx + bx = ad - ad + bc
x(d + b) = bc
