10x-15y=10, 4x+6y=0
First I would reduce the equations
10x - 15y = 10 ---> 2x - 3y = 2
4x + 6y = 0 -----> 2x + 3y = 0
Of course the easiest way from here would be to add them
that is, using elimination, BUT ...
you wanted substitution, so form the first 2x = 2 + 3y
sub that into the 2nd
2x + 3y = 0
2 + 3y + 3y = 0
6y = -2
y = -1/3
sub back into 2x = 2 + 3y
2x = 2 + 3(-1/3) = 1
x = 1/2
I need help! I am confused! Algebra
solve using substitution or elimination.10x-15y=10 4x+6y=0

Scooter Fun and Skoot Zoom are electronic scooter rental companies.
Scooter Fun charges a $15 deposit plus $5 per hour rental fee.
Skoot Zoom charges a $10 deposit plus $10 per hour rental fee.
The system of equations represents the cost, y, for renting a scooter for x hours.
y = 5x + 15
y = 10x + 10
What is the solution to the system of equations? Type your answer as an ordered pair. What does it mean in the context of this problem?
