x = number of dimes Jill has
y = number of dimes Joan has
"Jill has six times as many dimes as Joan"
x = 6y
together they have a total of 84 dimes
x+y = 84
------------------------------------------------
x+y = 84 ... focus on the first equation
6y+y = 84 ... replace x with 6y (x = 6y)
7y = 84
7y/7 = 84/7
y = 12
Use this to find x
x = 6y
x = 6*12 ... replace y with 12 (since y = 12 was found above)
x = 72
Jill has 72 dimes

The problem says:"Jill has 6*Joan, and it says that together, this is 6*Joan+Joan= 84. So let's call the dimes x:
6x+x= 84 Add x on left:
7x= 84 Now divide both sides by 7:
x= 12 Joan has 12 dimes, and Jill has:
12*6= 72
------------------------------
Check:
Joan has 12 and Jill has 72:
12+72= 84, we have the correct answer.
