Best ResponseYou've already chosen the best response.0yes thats what i got then you have to divide by 4. so then multiply by the reciprocal and i got 16/12 which simplifies to 4/3 right?

Best ResponseYou've already chosen the best response.0so z = 16/(3*4) = 16/12 = 4/3

Best ResponseYou've already chosen the best response.0if you put them back in, then 10/3 + 4*(4/3) =  2
