Question 953410
Let x = the smallest number, 2x-6 = the largest number, and (2x-6)-10 = the middle number. Set up an equation.


{{{x+2x-6+2x-6-10=68}}}


Now solve for x.


{{{3x-6+2x-6-10=68}}}
{{{5x-6-6-10=68}}}
{{{5x-12-10=68}}}
{{{5x-22=68}}}
{{{5x=90}}}
{{{x=18}}}


So we have the smallest number. Now let's plug those in the other two expressions to find the other two numbers.


{{{2x-6}}}
{{{2*18-6}}}
{{{36-6}}}
{{{30}}}
~~~~~~~~
{{{2x-6-10}}}
{{{2*18-6-10}}}
{{{36-6-10}}}
{{{30-10}}}
{{{20}}}

So the smallest number is 18, the middle number is 20, and the largest number is 30.

Hope I helped!
