Answer:
- Carpentry = 12 hours
- Blacksmithing = 18 hours
Step-by-step explanation:
Question wants to know the number of hours se worked at each.
This is a simultaneous equation problem.
Assume the carpenter job is x and the blacksmith is y.
x + y = 30
20x + 25y = 690
Substitution:
x + y = 30
y = 30 - x
20x + 25y = 690
20x + 25(30 - x) = 690
20x + 750 - 25x = 690
-5x = 690 - 750
-5x = -60
x = -60/-5
= 12 hours for carpentry
y = 30 - x
= 30 - 12
= 18 hours for blacksmithing
