Answer :
Answer: aircraft A has 212 seats and aircraft B has 104 seats
Step-by-step explanation:
Aircraft B: x seats
Aircraft A: x+108 (108 more than B)
Total seats on both is 316.
So, x+108+x = 316
Combine like terms
2x+108=316
Subtract by 180 both sides
2x=316-108 = 208
Divide by 2 on both sides
x = 104 seats (B)
x+108=104+108=212 (A)
