Solution:
Q1: 7
Q2: 2
x=6 seat boats y=8 seat boats {6x+8y=58 6x+8y= 58 <- { x+y=9 (multiply by -6)--> -6x-6y=-54 <-(add the two equations) 2y= 4 x+(2)=9 y= 2 x=7 X=7,Y=2 (7 six seat boats, and 2 nine seat boats!)
About me: I want to thank mmy big brother for showing me the new stuff he learns in school like how to do this problem.

Solution:
Q1: 7
Q2: 2
If all 9 boats have 6 seats we would fill only 54 people. If 2 boats out of 9 have two more seats each we would fill all 58 peaople. So we need 7 boats with 6 seats and 2 with 8.

Solution:
Q1: There are 2 8-seated boats
Q2: There are 7 6-seated boats
We got our answer by multiplying a handful of numbers. First we tried 8X5 and 6X3 but that was only 8 boats so we knew we were wrong.We were really puzzled but we kept trying number after number until we got 8X2= 16 2+7=9 6X7=+42=58

Solution:
Q1: 7 boats with 6 seats
Q2: 2 boats with 8 seats
2x8=16 58-16=42 So this tells me that I need 2 boats with 8 seats and 7 boats with 6 seats. And so 7+2=9 so that would be 9 boats.
