Answer 1

Ответ:один,просто первый ответ дробью,а второе десятичной))

Answer 2

The expression you provided is:

3 + 5x + (6 1/4 - 7x) - y

To simplify this expression, you can combine like terms. First, distribute the negative sign inside the parentheses:

3 + 5x + 6 1/4 - 7x - y

Now, combine the x terms:

(5x - 7x) = -2x

So the expression becomes:

3 + 6 1/4 - 2x - y

Now, add 3 and 6 1/4:

3 + 6 1/4 = 9 1/4

So the simplified expression is:

9 1/4 - 2x - y

You can leave it in this form, or if you want to express it as a single fraction, you can find a common denominator:

9 1/4 = 37/4

So the fully simplified expression is:

(37/4) - (8x/4) - (4y/4)

Now, combine the fractions:

(37 - 8x - 4y)/4

So, the simplified expression is:

(37 - 8x - 4y)/4
