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).
