There are two "is" in the question so there are three equivalent expressions.

The three expressions are:

A: 2*x - 2;

B: x - something, where the something is not specified;

and C: 48.

Then

A and B: 2*x - 2 = x - something - which cannot be solved;

B and C: x - something = 48 - which cannot be solved; ;

and A and C: 2*x - 2 = 48 which gives 2*x = 50 or x = 25.
