    x = 1.6, y = - 1.6 or your Answer (1.6, - 1.6)

    Step-by-step explanation:

    Substitute y = 1.5 x - 4 into the second equation:

    {y = 1.5 x - 4

    1.5 x - 4 = - x

    In the second equation, look to solve for x:

    {y = 1.5 x - 4

    {1.5 x - 4 = - x

    1.5 x - 4 = (3 x) / 2 - 4:

    { (3 x) / 2 - 4 = - x

    Add x + 4 to both sides:

    {y = 1.5 x - 4

    { (5 x) / 2 = 4

    Multiply both sides by 2/5:

    {y = 1.5 x - 4

    {x = 8/5

    Substitute x = 8/5 into the first equation:

    {y = - 1.6

    {x = 8/5

    Collect results in alphabetical order:

    Answer: {x = 8/5, y = - 1.6
