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
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?
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
true.....okay i kinda get it...
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)
so you now have two equations in two unknowns
x + y = 35 y + 7 = 4(x - 7) you should be able to solve these to find x and y.
yeah but x can = 35-y
so.....i'll plug it in
yes - you can solve using that method
okay.....so i got y= 19.6 and x = 15.4 correct?
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?
my math is wrong....just a min. please
yes - that matches my answers
