***PLEASE HELP ASAPPPPPPPP, I WILL BECOME A FAN AND GIVE YOU A MEDAL*** This is from Algebra 2: Brad can make 4 key chains in an hour. Velma can make only 3 key chains in an hour, but she already has 6 completed key chains. Explain to Brad how he can use a system of equations to determine when he will have the same number of key chains as Velma.
