I assume you want to solve for "x".
---
1.(x+a)/b + b=A
Multiply thru by b to get:
x+a + b^2 = Ab
x = Ab - a - b^2
-------------------------
2.bx+a=dx+c
bx-dx = c-a
x(b-d) = c-a
x = (c-a)/(b-d)
-------------------------
3.cx-b=ax+d
cx-ax = d+b
x(c-a) = d+b
x = (d+b)/c-a)
===================
Cheers,
Stan H.
