-2x + 6y = 6
6y - 6 = 2x
6(y-1) = 2x
(1/2) * 6(y-1) = 2x * (1/2)
x = 3(y-1)
------------
If, x = 3(y-1),
-7 * 3(y-1) + 8y = -5
-21 * (y-1) + 8y = -5
-21y + 21 + 8y = -5
21 + 5 = 21y - 8y
26 = 13y
y = 26/13
Therefore: y=2.
----------
If y=2,
x = 3(2-1) = 3
-----------
Answers:
x=3 and y=2.

Answer:</u></h2>
Jared and Pedro walked a total of <u>4.3 miles</u>
<h2><u>
Step-by-step explanation:</u></h2>
- The equation for distance is <u>speed = distance ÷ time.</u>
- Rearrange the equation to make distance the subject:
<em>(multiply both sides by time)</em>
<em> </em><u>Distance = Speed × Time</u>
- Convert your numbers into suitable units:
1 mile ÷ 15 = <u>0.06m/minute</u>
- Finally, substitute the numbers into the equation and solve:
Distance = 0.06 × 65 = <u>4.3miles</u> (rounded to the nearest decimal place)
