75 weeks

The amount of water in the two tanks will be the same in 75 weeks.

Step-by-step explanation:

x= how many weeks so find x

step one:

300 - 3x = 450 - 5x            -3x + 5x = 2x

       +5x            +5x

step 2:

300 + 2x = 450

-300          -300       450 - 300 = 150

step 3:

          2x = 150      150 / 2 = 75

step 4:

             x = 75
