For this case, what you should know is that Sue Jones insurance covers half of the expenses. Equivalently, her insurance covers:
10/20 = 1/2 = 0.5
Therefore, we have then that
a. for Albert
0.5 * (12000) = $ 6000
b. for Sam
0.5 * (8000) = $ 4000
c. total
The sum of the results of parts a and b
$ 6000 + $ 4000 = $ 10,000
answer
$ 6000
$ 4000
$ 10,000
The equation for the situation is 
The solution to the equation is 
First, you must set up the equation.

Then, you must simplify the terms.

Next, subtract 5.7 on both sides.

Finally, divide 5 on both sides
