Beakers X and Y contain some water. If 50 ml of water is transferred from Beaker X to Beaker Y, there will be 3/7 as much water in Beaker X as in Beaker Y. IF 100 ml
of water is transferred from Beaker Y to Beaker X, there will be 4 times as much
water in Beaker X as in Beaker Y. How much water is there in Beaker X?

140 ml

Step-by-step explanation:

Let x be the amount of water in Beaker X and y be the amount of water in Beaker Y.

Then we get following equations:

First part

Second part

Substitute x in first equation:

Then finding x:

Initial amount of water in Beaker X is 140 ml, in Beaker Y is 160 ml

your answer would be 12

f(x)=4
