Answer
Find out the how many plants will be in each row.
To prove
Let us assume that the number of plants in each row be x.
As given
Gavin buys 89 blue pansies and 86 yellow pansies
he will plant the flowers in 5 rows with an equal number of plants in each row.
Total number of flowers Gavin buys = 89 + 86
= 175
The number of plants in each row

x = 35
Therefore the number of plants in each row be 35 .
