Amount of money Judy has a given time = 20 + 6x      where x = #weeks

Amount ida has = 172 - 4x

When are they equal?

20 + 6x = 172-4x

10x=152

x = 15.2 weeks

20 + 6n  = 172 + 4n      where n is the number of weeks it will take them to have the same amount

Subtract  4n, 20 from both sides

2n  =   152        divide  b 2

n  =  76  weeks
