Let x = the first (smallest) integer, then (x+2) is the next consecutive integer and (x+3) is the third (largest) consecutive integer.
2x%2B3%28x%2B2%29+=+126 "...the sum of twice the smallest integer and three times the largest is 126."
2x%2B3x%2B6+=+126
5x%2B6+=+126 Subtract 6 from both sides.
5x+=+120 Divide both sides by 5.
x+=+24 and x%2B1+=+25, x%2B2+=+26
The three consecutive integers are: 24, 25, and 26.

What are three consecutive integers such that the sum of twice the smallest and three times the largest is 126?

Step 1. Let n be an integer (smallest integer), n+1 and n+2 (largest integer) be the next two consecutive integers.

Step 2. Let 2n be twice the smallest integer.

Step 3. Let 3(n+2) be three times the largest integer.

Step 4. Then 2n%2B3%28n%2B2%29=126 since the sum of twice the smallest and three times the largest is 126.

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

2n%2B3%28n%2B2%29=126

2n%2B3n%2B6=126

5n%2B6=126

Subtract 6 from both sides of the equation

5n%2B6-6=126-6

5n=120

Divide 5 to both sides of the equation

5n%2F5=120%2F5

n=24

With n=24, then n%2B1=25 and n%2B3=26

Check sum...2%2A24%2B3%2A26=126 which is a true statement.

Step 6. ANSWER: The numbers are 24, 25, and 26.

I hope the above steps were helpful.
