***ALGEBRA 2*** ***WILL GIVE MEDAL TO YOU AND BECOME FAN*** 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.

    let y be the amount of total key chains they have and x be the number of hours in the project how would you set it up after that?

    4x = y 4x = 3x - 6

    both equations are right but the second equation is what you get after subbing 4x for y

    so you would subtract 3x on the right and on the left and your left with x = 6?

    oh and one more thing its not 3x-6 its 3x+6 on the first step since she already has 6

    Let t be the number of hours when the total production of keys from Rad and Thelma are equal. 4t = 3t + 6 t = 6 hours when both workers have produced 24 keys
