2х + 6 = 7x - 14
What’s the answer?

Step-by-step explanation:

=> 2x+6 = 7x-14

Subtracting 2x to both sides

=> 6 =7x-2x-14

=> 6 = 5x-14

Adding 14 to both sides

=> 6+14 = 5x

=> 20 = 5x

=> 5x = 20

Dividing both sides by 5

=> x = 20/5

=> 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

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
