The sum of two numbers is 56. the larger number is 7 less than 3 times the smaller number. Find the smaller number.

smaller number  x
larger number  56x
56x = 3x  7
solve for x
you should get
smaller = 15.75
larger = 40.25
check:
three times the larger  7 = 3(15.75)  7 = 40.25
which was the larger.
