Using a system of equations, it is found that Peter had $48 at first.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Peter's money.
- Variable y: Henry's money.
The ratio of peters money to henrys money is 4 : 3, hence:

After Peter spent $12, they had the same amount, hence:
y = x - 12.
Then, replacing in the ratio:


4(x - 12) = 3x
x = 48.

If the ride cost $9 then the miles will be 3 miles.
Step-by-step explanation:
In this question we are given:
Cost of one cab ride R = $3
Additional Cost per mile M = $2
So, Total cost of Cab Ride = $3 + $2M
If cost of cab ride is $9 then we need to find the miles
$3 + $2M = $9
Solving
$2M = $9 - $3
$2M = $6
=> M = $6/$2
M = 3 miles
So, if the ride cost $9 then the miles will be 3 miles.
