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

#1**+5 **

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
