Put the numbers in the given equation and solve for k.
... $11 = k·(8 €)
Divide by the coefficient of k:
... k = $11/(8 €) = 1.375 $/€
Then your equation is ...
... y = (1.375 $/€)x
_____
It is fairly common to leave the units out of such equations, assuming that everyone understands that x is in euros and y is in dollars and the conversion factor includes a unit change from euros to dollars. Thus, you might expect to see ...
... y = 1.375·x

Answer: 
Step-by-step explanation:
For this exercise it is important to remember that:
1. The Addition property of equality states that:
If
, then 
2. The Subtraction property of equality states the following:
If
, then 
3. The Division property of equality states that:
If
, then 
4. The Multiplication property of equality states the following:
If
, then 
Then, having the following equation given in the exercise:

You need to solve for the variable "r" in order to find its value.
In order to solve for "r", you must apply the Addition property of equality adding 14 to both sides of the equation.
Therefore, you get the following solution:
