Answer:
20 days
Step-by-step explanation:
t = time required by one worker to complete the job alone
(t+8) = time required by the other worker
So:
7.5/ t + 7.5/ (t + 8) = 1
Solve for t.
...
t = 12 days, the first guy working alone
The other worker would finish the job in 20 days.

Explanation:</h2>
Here we have the following system of linear equations in two variables:
So if you graph these two equations you will get two lines with different slopes. The question is:
<em>What is the result of subtracting the second equation from the first?</em>
So this can be written mathematically as:
So the result of subtracting the second equation from the first is:
and from this we can calculate y.
