If 3 times the smaller of two consecutive integers is added to 4 times the larger, the result is 102, Find the larger integer.

Step 1. Let n be one integer and let n+1 be the next consecutive integer.

Step 2. Let 4(n+1) is 4 times the larger integer

Step 3. Let 3n is 3 times the smaller integer

Step 4. 3n+4(n+1)=102 3 times the smaller of two consecutive integers is added to 4 times the larger, the result is 102

Step 5. The following steps will solve the equation in Step 4.

Done!



With n=14 , then n+1=15

Check 3*14+4*15=102 or 102=102 which is a true statement

Step 6. The integers are 14 and 15 where 15 is the larger integer.

I hope the above steps were helpful.
