Question 1003308


First number = {{{x}}}
Second number = {{{x + 8}}}
Third number = {{{3x - 3}}}
Our equation is: {{{3x - 3 = (x + 8) + 15}}}

Solving for {{{x}}} we get 
{{{3x - 3 = x + 23}}}
{{{3x - x = 3 + 23}}}
{{{2x = 26}}}
{{{x = 13}}}

So, the first number is {{{13}}}.
The second number is {{{13+8=21}}}.
The third number is {{{3*13-3=36}}}.
