An ATM machine issues $10 and $20 notes only. On a particular day 66 notes had been issued, for a total value of 8970. Two simultaneous equations that can be obtained from this information are: 1+1=66
10x +20y =970
(a) What do r and y represent in these equations?
(b) Solve the equations to work out how many of each kind of note were issued​
