Answer:
12 hours
Step-by-step explanation:
Let the number of hours be represented as h.
Sarah's surfboards charges a fee of $60 to rent a surfboard and then $10.50 per hour.
Mathematically ,
60 + 10.50h
Sally's surfboards does not charge a fee, but they cost $15.50 per hour
Mathematically,
15.50h
Equating both equations together
60 + 10.50h = 15.50 h
Collect like terms
60 = 15.50h - 10.50h
60 = 5h
h = 60/5
h = 12 hours
Therefore, the number of hours that the cost will be the same to rent a surfboard for each shop is 12 hours.
Answer:

Step-by-step explanation:
the right answer!
Do you mean 3x+2=7
3x=7-2
3x=5
x=5 over 3
x=1.6
3y+1=4y-6
1+6=4y-3y
y=7
2+6x=1-x
6x+x=1-2
7x=-1
x= -1/7
5y+4=4y+5
5y-4y=5-4
y=1
