IF y represents a number then how can you write an expression for negative two times the sum of y and 7

In the given problem variable y is taken for unknown number.

We need to write an expression for "negative two times the sum of y and 7".

Let us break the given statement into smaller parts to understand it better.

" Negative two"

Negative is the minus sign and 2 is a number. So, negative two is - 2.

"times"

Times represents multiplication operation *.

"the sum of y and 7".

The sum represents addition operation. Therefore, the sum of y and 7 can be expressed y+7.

Let us write expression for complete given statement.

Negative two times the sum of y and 7 = - 2 * (y+7).

We can write, expression without times * symbol as.

-2 (y+7).
