Answer:
No you cannot.
Step-by-step explanation:
Let c be the amount of time it takes each machine to make 1 cockpit, and p be the amount of time it takes each machine to make 1 propulsion system.
For Machine A, we have 4 cockpits; this would take 4c time. We also have 6 propulsion systems; this would take 6p time. Together it takes 26 hours; this would give us
4c+6p=26.
For Machine B, we have 8 cockpits; this would take 8c time. We also have 12 propulsion systems; this would take 12p time. Together it takes 56 hours; this would give us
8c+12p=56
This gives us the system
To solve this, we want the coefficients of one of the variables to be the same. To make the coefficients of c the same, we can multiply the top equation by 2:
To cancel c, we will subtract the second equation from the first one. However, this also cancels p:
We get a statement that is not true; thus the system has no solution, and we cannot solve for a unique amount of time.
