    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
