count the deposits, and count the amounts:
If there were x deposits at $5, and y at $3.50, then we know
x+y=14
5x+3.50y=59.50
Now just plug and chug.
If there were x deposits at $5, and y at $3.50, then we know
x+y=14
5x+3.50y=59.50
Now just plug and chug.

Steve said that x+y = 14..
Steve also explained to you.
*How are you confused on what numbers to multiply to get 59.50..?*
if x+y = 14 then it would be
x= 7
y=7
5x means 5 multiplied by x and x is 7.
5 times 7 is 35
so now its 35 + 3.50y
3.50 times 7 is 24.5
so now 35 + 24.5 = 59.5 or 59.50
