x=13

y=13

Step-by-step explanation:

9x + 14y = 299

2x + 10y = 156

Use elimination

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

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
