Joe father is 45

Joe father is 2x + 15

2x + 15 = 45
2x + 15 (-15) = 45 (-15)
2x = 30
2x/2 = 30/2
x = 15

Joe is 15

hope this helps
So, you make your equation 2x+15=45, because of the given numbers. Now you solve for x.
First, you subtract 15 from both sides, which gives you 2x=30.
Then you divide both sides by 2, which give you x=15.
So, Joe is 15 years old.
