    Solution for 2x+1=5x-5 equation

    Simplifying

    2x + 1 = 5x + - 5

    Reorder the terms:

    1 + 2x = 5x + - 5

    Reorder the terms:

    1 + 2x = - 5 + 5x

    Solving

    1 + 2x = - 5 + 5x

    Solving for variable 'x'.

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

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

    1 + 2x + - 5x = - 5 + 5x + - 5x

    Combine like terms: 2x + - 5x = - 3x

    1 + - 3x = - 5 + 5x + - 5x

    Combine like terms: 5x + - 5x = 0

    1 + - 3x = - 5 + 0

    1 + - 3x = - 5

    Add '-1' to each side of the equation.

    1 + - 1 + - 3x = - 5 + - 1

    Combine like terms: 1 + - 1 = 0

    0 + - 3x = - 5 + - 1

    -3x = - 5 + - 1

    Combine like terms: - 5 + - 1 = - 6

    -3x = - 6

    Divide each side by '-3'.

    x = 2

    Simplifying

    x = 2
