Question 678942
Mutiply the entire equation by x to be rid of the fractions
{{{x(3/x) + x(3/x) - 5x = 3xx - x(12/x) - 5x}}}
...
{{{3 + 3 - 5x = 3x^2 - 12 - 5x}}}
...
{{{0 = 3x^2 - 12 - 5x + 5x - 3 - 3}}}
...
{{{0 = 3x^2 - 18}}}
...
{{{0 = 3(x^2-6)}}}
{{{0 = x^2 - 6}}}
{{{x^2 = 6}}}
{{{sqrt(x^2) = sqrt(6)}}}
{{{x = sqrt(6)}}}
