Question:
The number of trees planted by the Alpine Nursery in April was 3 more than twice the number of trees planted in March. If 71 trees were planted in april, write and solve an equation to find how many trees were planted in March.

 

 

Hi Allison,

If you are going to write an algebraic equation to solve this problem you need first to decide what the variable will reprersent. Since you are asked to find how many trees were planted in March it seems reasonable to let that be the variable.

Let x be the number of trees that were planted in March.

The problem now says that the number of trees planted in April (71) was 3 more than twice the number of trees planted in March. Since the number planted in March was x this says

71 is 3 more than 2x In other words 71 = 2x + 3

Now can you find the value of x?
