Question

2x+1/a+3x+1/a-x-2/a​

Answer 1

..............=4х+2/а-2/а=4х

Answer 2

It looks like you've provided an algebraic expression with variables. The expression you've given is a bit unclear due to the formatting. If I understand correctly, you have the following expression:

(2x + 1) / a + (3x + 1) / a - (x - 2) / a

If that's correct, then you can simplify this expression by combining the terms with common denominators:

(2x + 1 + 3x + 1 - x + 2) / a

Now, combine the like terms in the numerator:

(4x + 4) / a

You can factor out a common factor of 4 from the numerator:

4(x + 1) / a

So, the simplified expression is:

4(x + 1) / a
