Question

Attachment.

Answer 1

lets call the amount of water in the container with less water x, and the amount of water in the other one y.
then we can say:

x + y = 35

Answer 2

so if we pour 7 quarts from container with x into container with y, how much water will be left in the container that had x to start with?

Answer 3

x-7=y+7?

Answer 4

x-7 is how much is left in the original container
x+7 is how much will now be in the other container
they are not equal however

Answer 5

true.....okay i kinda get it...

Answer 6

it says the container with more water now contains 4 times as much as the other one, so we can say:

y + 7 = 4(x - 7)

Answer 7

so you now have two equations in two unknowns

Answer 8

x + y = 35
y + 7 = 4(x - 7)

you should be able to solve these to find x and y.

Answer 9

yeah but x can = 35-y

Answer 10

so.....i'll plug it in

Answer 11

yes - you can solve using that method

Answer 12

okay.....so i got y= 19.6 and x = 15.4 correct?

Answer 13

that does not match my answers. maybe if you describe your steps here then I can help you spot where you (or I) made a mistake?

Answer 14

my math is wrong....just a min. please

Answer 15

x=14 y=21?

Answer 16

yes - that matches my answers

Answer 17

thanks!
