Answer:
There were 34 trees planted in March
Step-by-step explanation:
* Lats explain how to solve the problem
- The number of trees planted by the alpine Nursery in April was
three more than twice the number of trees planted by the nursery
in March
- Assume that the number of trees planted in March is x
∵ The number of trees in April was three more than twice the
number of trees on March
∵ The number of trees on March was x
∴ The number of trees in April = 2x + 3
- There were 71 trees planted in April
∵ The number of trees were planted on April was 71
∵ The number of trees in April = 2x + 3
∴ 2x + 3 = 71
- Subtract 3 from both sides
∴ 2x = 68
- Divided both sides by 2
∴ x = 34
∵ x represents the number of trees were planted in March
∴ There were 34 trees planted in March
