    me memory is coming back a little

    Step-by-step explanation:

    Simplifying

    3x + 5 = 9x + - 17

    Reorder the terms:

    5 + 3x = 9x + - 17

    Reorder the terms:

    5 + 3x = - 17 + 9x

    Solving

    5 + 3x = - 17 + 9x

    Solving for variable 'x'.

    Move all terms containing x to the left, all other terms to the right.

    Add '-9x' to each side of the equation.

    5 + 3x + - 9x = - 17 + 9x + - 9x

    Combine like terms: 3x + - 9x = - 6x

    5 + - 6x = - 17 + 9x + - 9x

    Combine like terms: 9x + - 9x = 0

    5 + - 6x = - 17 + 0

    5 + - 6x = - 17

    Add '-5' to each side of the equation.

    5 + - 5 + - 6x = - 17 + - 5

    Combine like terms: 5 + - 5 = 0

    0 + - 6x = - 17 + - 5

    -6x = - 17 + - 5

    Combine like terms: - 17 + - 5 = - 22

    -6x = - 22

    Divide each side by '-6'.

    x = 3.666666667

    Simplifying

    x = 3.666666667

    x≈ 3.7

    Step-by-step explanation:

    Subtract 3x from both sides and add 17 to both sides. That leaves you with 22=6x. Divide both sides by 6 to isolate the variable and you should get x equals about 3.7.
