4.5(8 - x) + 36 = 102 - 2.5(3x + 24) 
36 - 4.5x + 36 = 102 - 7.5x - 60
72 - 4.5x = 42 - 7.5x
-4.5x + 7.5x = 42 - 72
3x = - 30
x = -30/3
x = -10 <=== 
Hope this helps!

Answer:
6hours
Step-by-step explanation:
From the given information:
Suppose it took Karl x hours to retile her bathroom, 
Then it will take Della 3 hours longer i.e (3+x) hours
If Della and Karl work together or will take them 2 hours 
The objective is to determine how long it will take Delia to retile the bathroom alone?
∴



By cross multiplying, we have:
2(2x+3) = 3x+x²
4x + 6 = 3x + x²
3x + x² - 4x - 6
x² - x - 6 = 0
Using quadratic equation
x² -3x +2x - 6 = 0
x(x - 3) + 2(x - 3) = 0
(x +2) (x - 3) = 0
x + 2 = 0 or x - 3 = 0
x = -2 or x = 3
Since we are concerned about the positive integer,
Then, Karl = x = 3 hours while Della which is (3+x) = 3+3 = 6hours

Im pretty sure it’s going to be a, because when you divide by the -6 you’re supposed to switch the sign
