How do you solve this???

-3x = 12

Thanks!

x = -4

Step-by-step explanation:

First you need to find the common factor, which in this problem is 3. Then you need to divide the equation by the common factor which makes it -x = 4. We then need to multiply the equation by -1 to make x positive which makes it x = -4.

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
