Lets assume, Sally has X pound of potatoes in her pantry.
So, 4/3 of the potatoes Sally has in her pantry =
![(4)/(3)X](https://img.qammunity.org/2019/formulas/mathematics/high-school/3bql5ofo9uakgi7wmsxjtgs59c3t78p3hs.png)
Now, Sally needs 2/3 pound of potatoes and this 2/3 pound of potatoes is 1/3 pound more than that
![(4)/(3)X](https://img.qammunity.org/2019/formulas/mathematics/high-school/3bql5ofo9uakgi7wmsxjtgs59c3t78p3hs.png)
So the representing equation will be:
(subtracting
from both sides)
![(1)/(3)= (4)/(3)X](https://img.qammunity.org/2019/formulas/mathematics/high-school/kbzwh8edfppz7q5ez5bj15ppbcb1e6wa9e.png)
(multiplying both sides by 3)
So, Sally has
pound of potatoes in her pantry.
