Answer:

x = -, y = - 1/2

Step-by-step explanation:

- 4x + 11 = 15 \\  - 4x = 18 - 11 \\  - 4x = 4 \\ x =  \frac{4}{ - 4}  \\ \red{ \bold{ x =  - 1}} \\ x = 2y \\ 2y =  - 1 \\ \purple{ \bold{ y=  -  \frac{1}{2} }}

(21 + 34 + x + 25 + 37 + 22) / 6 = 30
(139 + x) / 6 = 30 .....multiply both sides by 6
139 + x = 30 * 6
139 + x = 180
x = 180 - 139
x = 41......so during week 3, she rode her bike 41 miles
