A certain number is 4 less than another number. If the sum is 46, find the numbers.

Step 1. Let n be one number.

Step 2. Let n-4 be another number.

Step 3. Then, n+n-4=46 since their sum is 46.

Step 4. Solving yields the following steps

2n-4=46

Add 4 to both sides of the equation

2n-4%2B4=46%2B4

2n=50

Divide by 2 to both sides of the equation

2n%2F2=50%2F2

n=25 and n-4=21. Also note that their sum is 46.

Step 5. ANSWER: The numbers are 21 and 25.

I hope the above steps were helpful.
