7 - (2x + 1) + 4x
please show solving steps as well

Step-by-step explanation:

Distribute the negative inside 2x+1

Remind that negative multiply negative must equal positive.

variables cannot sum/add/subtract with constants.

They must be the same terms.

Therefore, our answer is 2x+6

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
