Answer 2

To simplify the expression 3а + 1/7а + в/14ав - в + 1/2в, we need to combine like terms and perform any possible simplifications. Here's the step-by-step process:

Step 1: Combine like terms with the same variable 'a': 3а + 1/7а = (3 + 1/7)а = (21/7 + 1/7)а = (22/7)а

Step 2: Combine like terms with the same variable 'в': в/14ав - в + 1/2в = (1/14 - 1 + 1/2)в

Step 3: Simplify the expression for 'в': (1/14 - 1 + 1/2)в = ((1 - 14 + 7)/14)в = (-6/14)в = (-3/7)в

Now, the simplified expression is: (22/7)а - (3/7)в
