Answer:
mx -y = 4m -7
Step-by-step explanation:
Standard form is ...
ax +by = c
where a, b, c are mutually prime integers and a > 0.
If we assume m > 0, then we need to collect the variable terms on the right side of the equation, so the coefficient of x will be positive.
y -7 = mx -4m . . . . eliminate parentheses
-7 = mx -y -4m . . . . subtract y
4m -7 = mx -y . . . . . add 4m
mx -y = 4m -7 . . . . . . standard form
This is an improper. Perhaps you can fix it, so that I can assist you with it? I apologise.
the construction of fields of formal infinite series in several variables, generalizing the classical notion of formal Laurent series in one variable. Our discussion addresses the field operations for these series (addition, multiplication, and division), the composition, and includes an implicit function theorem.

"Sum" tells us it's an addition problem:
One term is 12 and the other is 9/x
SO
The expression is:
12+9/x
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.
