    subtracting 8 from both sides of the equation

    Step-by-step explanation:

    The first step is subtract 8 from both sides of the equation

    Then you take the square root of both sides of the equation

    Finally you divide from both sides op the equation by - 5

    -5x2+8=133

    -5x2 + 8 - 8 = 133 - 8

    -5x2 = 125

    -5x = √125

    -5x = 11.18

    -5x / - 5 = 11.18/-5

    x = 2.236
