    Simplifying

    3x + - 4y = 16

    Solving

    3x + - 4y = 16

    Solving for variable 'x'.

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

    Add '4y' to each side of the equation.

    3x + - 4y + 4y = 16 + 4y

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

    3x + 0 = 16 + 4y

    3x = 16 + 4y

    Divide each side by '3'.

    x = 5.333333333 + 1.333333333y

    Simplifying

    x = 5.333333333 + 1.333333333y
