For this case we have the following system of equations:

Equating the equations we have:

To find the solutions we factor the equation. To do this, we look for two numbers that, when multiplied, result in -3 and when added, result in -2.
These numbers are: -3 and +1

Thus, the factored equation is:

Then, the solutions for the variable "x" are:

We find the solutions for the variable "y":

Thus, the solutions are:

ANswer:

Is the greatest factor that two or more numbers have in common. One way to find the GCF is to make lists of the factors for two numbers and then choose the greatest factor that the two factors have in common.
Answer:
10
Step-by-step explanation:
1 / 3
What times x gives us y?
Hint 2 / 3
If we multiply each x-value by 10
we get to each corresponding y-value:
y=10x
The constant of proportionality is y= r x is 10
