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
oh yeah thats true
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
but yes after you get x=6
so how do i say this when using system of equations
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.
just put the numbers in the equation into words
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
is that it rob?
yep you dont have to solve for the other variable since its not asking for total
rob basically summed it up lol
thanks u guys
