Is this what you are trying to do:

f := (8 x + 2)/7 - (12 x - 3)/5 == -1

Solve[f, x]

Hello,

A good place to learn Wolfram Language is here Virtual Book

To reply to what you asked, here is an example. Notice the difference between = (Set) which sets the value of a variable, and == (Equal) which asserts equality. (There are also ways of producing a more typeset expression.)

In[1]:= equation = (8 x + 2)/7 - (12 x - 3)/5 == 1

Out[1]= 1/5 (3 - 12 x) + 1/7 (2 + 8 x) == 1

In[2]:= solution = Solve[equation, x][[1]]

Out[2]= {x -> -(1/11)}

In[3]:= x /. solution

Out[3]= -(1/11)
