To simplify the expression 1/3(3в-18)-2/7(7в-21), you can follow these steps:

1. Distribute the constants and coefficients inside the parentheses: 1/3 * 3в = в 1/3 * 18 = 6 2/7 * 7в = 2в 2/7 * 21 = 6

2. Now, rewrite the expression with the simplified terms: в - 6 - 2в + 6

4. Perform the subtraction and simplify further: -в + 0

The final simplified expression is simply: -в
