Answer:
(-5,-3)
Step-by-step explanation:
In this case to find the solution you could use substitution. This way you can solve without changing the equation over again.
(b - 2) - 3b = 4
b - 2 - 3b = 4
-2b - 2 = 4
-2b = 6
b = -3
Plug back in to find value a
a = (-3) - 2
a = -5
Check your answer before submitting
(-5) - 3(-3) = 4
-5 + 9 = 4
4 = 4

Answer: 9 miles per week</h3>
Explanation:
You divide the two values given to get 63/7 = 9.
We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".
You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.
