***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.

Answer 1

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?

Answer 2

4x = y
4x = 3x - 6

Answer 3

@acxbox22

Answer 4

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

Answer 5

oh yeah thats true

Answer 6

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

Answer 7

@acxbox22

Answer 8

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

Answer 9

but yes after you get x=6

Answer 10

oh

Answer 11

so how do i say this when using system of equations

Answer 12

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.

Answer 13

just put the numbers in the equation into words

Answer 14

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

Answer 15

is that it rob?

Answer 16

yep you dont have to solve for the other variable since its not asking for total

Answer 17

thanks man

Answer 18

rob basically summed it up lol

Answer 19

ya

Answer 20

thanks u guys
