If the average (arithmetic mean) of three numbers is 6, and the sum
of the two larger numbers is 16, what is the value of the smallest number?
:
3 numbers, a, b, c, (c is the smallest)
write an equation for each statement
:
= 6
multiply both sides by 3
a + b + c = 18
a + b + 0 = 16; (the 2nd statement)
------------------subtraction eliminates a and b, find c
c = 2 is the smallest number
