Question 460544: The sum of the ages of Joe and Jim is 92. Eight years from now, Joe will be twice Jim's age. Find Joe's present age?
Answer by JimboP1977(311) (Show Source): You can put this solution on YOUR website!
Joe's present age = X
Jim's present age = Y
X+Y=92 (1)
X+8 = 2*(Y+8) (2)
X+8 = 2Y+16 (2)
X = 2Y + 8 (2)
Substitute (2) into (1)
2Y+8+Y = 92
3Y+8 =92
3Y = 84
Y = 28
X =92-28
X = 64
Does this make any sense? Please get back to me.
