    Simplifying

    13 = 4x + 9

    Reorder the terms:

    13 = 9 + 4x

    Solving

    13 = 9 + 4x

    Solving for variable 'x'.

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

    Add '-4x' to each side of the equation.

    13 + - 4x = 9 + 4x + - 4x

    Combine like terms: 4x + - 4x = 0

    13 + - 4x = 9 + 0

    13 + - 4x = 9

    Add '-13' to each side of the equation.

    13 + - 13 + - 4x = 9 + - 13

    Combine like terms: 13 + - 13 = 0

    0 + - 4x = 9 + - 13

    -4x = 9 + - 13

    Combine like terms: 9 + - 13 = - 4

    -4x = - 4

    Divide each side by '-4'.

    x = 1

    Simplifying

    x = 1
