Question 885077: You plant a 14-inch hemlock tree in your backyard that grows at a rate of 4 inches a year and an 8-inch spruce tree that grows 6 inches a year. In how many years after you plant the trees will they be the same height? How tall will they be?
So far I have little equations that will help me solve this problem but I don't necessarily know what to do with them.
14 + 4y = height of the hemlock
8 + 6y = height of the spruce
It is preferred that they are solved in standard form. Thank's for your help.

since the two trees will be the same height set the two equal to one another
14 + 4y = 8 + 6y
6=2y
3=y 3 years
check
14+12=8+18
26=26
26 inches
