Question 967175
First list - Ages now: (plug in for answers)

Let x = be Ann's age now  
Let 5x =  Father's age now


Second list - Ages before: (to set up in equations)

x = Ann's age when she was born
5x+32 = Father's age when she was born


Set up an equation:

x = 5x+32
x-5x = 5x+32-5x (get rid of one numerical coefficent)
4x = 32 
__   __
4     4  (Divided by 4 on both sides)

x  =  8


Now plug in:


First listed values:

Ann's age now: x = 8 years old

Father's age now: 5x = 5(8) = 40 years old


Check: 

Father's age before + 8 years later = Father's age now
32 + 8 = 40 years 

which is 5x + 32 = 5(8) - 32 = 8 {Ann's age}
