Acontainer was 1/2 filled with water. when 200 ml of water was poured out, it became 1/3 full. find the capacity of the container in milliliters.

X=whole capacity
(x/2)=original amount
orginal amount-200=x/3
so
(x/2)-200=x/3
subtract x/2 from both sides
-200=(x/3)-(x/2)
make denomenators same
x/3 times 2/2=2x/6
x/2 tiimes 3/3=3x/6
now we have
-200=2x/6-3x/6
-200=-x/6
multiply both sides by 6
-1200=-x
multiply -1
1200=x

capacity is 1200 ml

There is no question, there is just the answer.
