Question 378574: Find three consecutive interges such that the sum of twice the smalles and 3 times the largest is 126
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Let x = smallest integer
x+1 = middle integer
x+2= largest integer
The equation is in the sentence "the sum of twice the smallest and 3 times the largest is 126". Translated, this means
2( ) + 3( ) = 126
2(x) + 3(x+2)=126
2x + 3x+6 = 126
5x+6=126
5x=120
x=120/5=24 smallest
x+1=25 middle
x+2=26 largest
Check:
2*24 + 3*26
48 + 78
126
It checks!!

Look for the link "Basic, Intermediate, and College Algebra: One Step at a Time" and select "Basic Algebra", "Chapter 1". My explanations were written for students who have trouble understanding math, and according to my own students they are a LOT easier to understand than traditional textbooks.
In addition, please look for my detailed SOLUTIONS to many of these exercises which are solved in the MATH IN LIVING COLOR pages that are found in the website!
