Answer:
337 Basic products; 694 Advanced products
Explanation:
You want the numbers of products that should be produced to run the factory at capacity if ...
- Basic takes 3 Assembly and 2 Finishing hours
- Advanced takes 2.4 Assembly and 2.4 Finishing hours
- Capacity is 2678 Assembly and 2341 Finishing hours
Setup
You add up the assembly and finishing hours and set them to their respective capacity limits.
3b +2.4a = 2678 . . . . . . . . assembly hours
2b +2.4a = 2341 . . . . . . . . . finishing hours
Solution
Subtracting the second equation from the first gives ...
(3b +2.4a) -(2b +2.4a) = (2678) -(2341)
b = 337 . . . . . . . . . . . simplify
2(337) +2.4a = 2341
2.4a = 1667 . . . . . . . . . subtract 674
a = 694.5833... . . . . . . divide by 2.4
Rounding down gives b = 337, a = 694.
The company should manufacture 337 Basic and 694 Advanced products to run at capacity.

Additional comment
There will be 1.4 hours left over in each department, not enough to produce another product of either kind.
