    Answer: x = 4

    Step-by-step explaintion : 2x - 10 = 10 - 3x

    Simplifying

    2x + - 10 = 10 + - 3x

    Reorder the terms:

    -10 + 2x = 10 + - 3x

    Solving

    -10 + 2x = 10 + - 3x

    Solving for variable 'x'.

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

    Add '3x' to each side of the equation.

    -10 + 2x + 3x = 10 + - 3x + 3x

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

    -10 + 5x = 10 + - 3x + 3x

    Combine like terms: - 3x + 3x = 0

    -10 + 5x = 10 + 0

    -10 + 5x = 10

    Add '10' to each side of the equation.

    -10 + 10 + 5x = 10 + 10

    Combine like terms: - 10 + 10 = 0

    0 + 5x = 10 + 10

    5x = 10 + 10

    Combine like terms: 10 + 10 = 20

    5x = 20

    Divide each side by '5'.

    x = 4

    Simplifying

    x = 4
