Answer:
Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let 
denote the number of rafts seating 3 people and 
the number of rafts seating 5 people. The total number of rafts is 13, so 
. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so 
.
It's always a good idea to put these equations under each other:
We can subtract the first equation three times from the second one to obtain 
Now, substitute this found value for into 
and we see that 
. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Your answer will be -23/8
Answer:
8x2y - 6x2 - 8xy2 - y2
Step-by-step explanation:
Equation at the end of step 1 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)
Step 2 :
Equation at the end of step 2 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)
Step 3 :
Equation at the end of step 3 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)
Step 4 :
Equation at the end of step 4 :
(((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)
Step 5 :
Equation at the end of step 5 :
(((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 6 :
Equation at the end of step 6 :
((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 7 :
Final result :
8x2y - 6x2 - 8xy2 - y2
