First = x
second = y
third = z
Rewrite the problem using those:
>>The sum of x,y, and z is 47.
y is half of x while z is 1 less than y.
Find the three numbers?<<
Look at the first part:
>>The sum of x,y, and z is 47.<<
That says x + y + z = 47
Look at the second part:
>>y is half of x<<
That says y =
x
Look at the third part
>>while z is 1 less than y.<<
That says z = y - 1
So you have this system of equations:
Solve that system. You'll know if you have the right
answer because y will be half of x, and z will be one
less that y, amd when you add them all you'll get 47.
