Y varies directly with x. Find x when y = -12, if y = 4 when x = 3.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
