**MathMate**, Saturday, October 3, 2009 at 8:32amFive times the smallest of three consecutive odd integers is ten more than twice the longest.

Let the middle integer be x.

then the three odd integers are x-2, x, x+2.

Five times the smallest = 5(x-2)

ten more than twice the longest= 2(x+2)+10

so

5(x-2) = 2(x+2) + 10

5x-10 = 2x+4 + 10

5x-2x = 4 + 10 + 10

3x = 24

x = 8

The three integers are 6,8 and 10.

You can solve the other problems in the same way. If you have difficulties, post what you have done.
