The numbers are 9 and 45. a = 5b a - 18 = 3b which becomes a = 3b + 18 Therefore: 5b = 3b + 18 18 = 2b b = 9 a = 45

If B equals 8, then the equation is: 20-8=? The answer is 12.
64 subtracted from 18 = 46
42 subtracted by 60 = -18

The numbers that are subtracted are called subtrahends. (if a - b = c then a is the minuend, b is the subtrahend and c is the result.)
