Alright, lets gets tarted.
Suppose there are x rows of tomato plants Krystyn make.
Again suppose there are n plants in each row.
We could find total plants by multiplying number of plants in each row with number of rows.
Hence total number of plants will be =
But as per question, total number of plants are 54. It means
Now, the number of plants in each row was 3 more than the number of rows means
Putting this value of n in first equation we made
Subtracting 54 in both sides
Factoring
Means x = 6 or x = -9
The number of rows can not be negaive.
Hence x = 6
It means number of rows of tomato plants will be 6. : Answer
Hope it will help :).
