The difference of two numbers is 17, and their sum is 85. Find the smaller of the two numbers

Step 1. Let y be the larger number and x be the smaller number.

Step 2. y-x=-x+y=17 (given the difference of two numbers is 17.

Step 3. x+y=85 (sum is 85)

Step 4. Steps 2 and 3 form a system of linear equations.

Add two equations together to get

Then x=85-y=85-51=34

Step 5. ANSWER: The smaller number is 34.

I hope the above steps were helpful.
