Question

The sum of two numbers is 3 more than three times of the smaller. if the difference of the numbers is 5, find the numbers.​

Answer 1

Step-by-step explanation:

step 1. the difference between two numbers was 5, so:

BIG = Little plus 5.

step 2. 3 Littles plus 1 Big equals 33.

step 3. 3 Littles + (1 Little plus 5) equals 33 <== a logical substitution replacing Big.

Now we logically combine the numbers and the Littles separately.

step 4. 4 Littles equal (33 - 5) , or 28. wow, we could do this in the 6th grade.

step 5. 1 Little equals 7 because (4 times 7) equals 28.

step 6. BIG equals (7 plus 5), which is 12.
