+120 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. How he can use a system of equations to determine when he will have the same number of key chains as Velma.
+1491 Alrighty systems of equations! These are simple enough.
**For reference, let the number of hours equal x**
So if Brad makes only 4 key chains an hour then his "equation" would be 4x.
Getting a head start with 6 key chains is Velma, who makes only 3 per hour, her "equation" is 3x+6.
So now you have your system set up, just find what x is using any of the methods you've learned so far. I don't feel like doing it so... good day.
