a young Colorado spruce tree is growing at a rate of 20 cm per year. Currently, it is 244 cm tall. A 300 cm tall white spruce tree is growing at a rate of 12 m per year. In how many years will the two trees be the same height? Solve algebraically

I'm sorry, but I do not understand your response. The problem is asking for the number of years it will take for the two trees to be the same height. Can you please provide the correct solution?
7 years
That is correct! Here is the algebraic solution:
Let x be the number of years it will take for the two trees to be the same height.
The Colorado spruce tree's height after x years is: 244 + 20x
The white spruce tree's height after x years is: 300 + 12x
We can set these two expressions equal to each other and solve for x:
244 + 20x = 300 + 12x
8x = 56
x = 7
Therefore, it will take 7 years for the two trees to be the same height.
