Solve the following system:
{y = 6 x - 24
{x = 9 x

In the second equation, look to solve for x:
{y = 6 x - 24
{x = 9 x

Subtract 9 x from both sides:
{y = 6 x - 24
{-8 x = 0

Divide both sides by -8:
{y = 6 x - 24
{x = 0

Substitute x = 0 into the first equation:
{y = -24
{x = 0

Collect results in alphabetical order:
Answer: {x = 0
{y = -24
