Answer: 21
Explanation:
We start by trying to figure out what age you were to start.
We represent your current age with x. So the question now reads:
x-6=(x+4)1/2
We simplify each side with distributive property.
x-6=1/2x +2
subtract 1/2x from each side to isolate the variable. And add 6 to each side
1/2x=8
Multiply each side by 2
x=16
Therefore you are currently sixteen and "five years from now" you will be 21.
