Question 178022: You plant a 14-inch tree that grows 4 inches per year and an 8-inch tree that grows 6 inches per year. How many years after you plain the trees will the two trees be the same height? How tall will each tree be?

You can put this solution on YOUR website!
Let x=no. of years for the trees to be of same height
Then, after x years, the 14-inch tree will be 14+4x inches tall; the 8-inch tree will be 8+6x inches long.
So,

4x+14=6x+8
14=2x+8
2x=6
x=3 years Ans.
