Answer:
We know that:
The tree was 1.85 meters tall.
After several years, an unknown amount of years, the tree is 5.30 meters tall.
To show the meters the tree has grown, we just have to express:
Final highness = x + Initial highness; where x refers to the unknown meters that the tree has grown.
Now, we isolate x and solve:
5.30 = x + 1.85
5.30 - 1.85 = x
x = 3.45 m
Therefore, the tree has grown 3.45 meters. And equation that allow to find this result is 5.30 = x + 1.85.
