ANSWER
Paul and Matt will take 

to install the floor working together.
EXPLANATION
First, calculate Paul's rate, which is

Next, calculate Matt's rate, which is,

Let us assume that, Paul and Matt took 

to do the work together.
Then, the rate of working together is,

Now, add the individual rates and equate to the rate of working together to form an equation that will help us solve for x.

Simplify the left hand side


We reciprocate both sides to get (You could have also done cross multiplication).

Assuming you meant Mazo = Maisel,
You start from the bottom: 
Amelia is 10 years younger than 17-year-old Maisel.
Amelia is 7 years old. (17-10)
Ernie is 2 years older than 7-year-old Amelia.
Ernie is 9. (2+7)
Alana is 4 years older than 9-year-old Ernie.
Alana is 13 years old. (4+9)

Answer:
y = 3x - 11      
Step-by-step explanation:
Step 1:
y = mx + b          Slope Intercept Form
Step 2:
y = 3x + b        Input Slope
Step 3:
- 5 = 3 ( 2 ) + b        Input x and y values
Step 4:
- 5 = 6 + b          Multiply
Step 5:
- 11 = b        Subtract 6 on both sides
Answer:
y = 3x - 11
