    Answer:

    x=7

    Step-by-step explanation:

    Solution for 3x-10-x=4 equation:

    Simplifying

    3x + -10 + -1x = 4

    Reorder the terms:

    -10 + 3x + -1x = 4

    Combine like terms: 3x + -1x = 2x

    -10 + 2x = 4

    Solving

    -10 + 2x = 4

    Solving for variable ‘x’.

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

    Add ’10’ to each side of the equation.

    -10 + 10 + 2x = 4 + 10

    Combine like terms: -10 + 10 = 0

    0 + 2x = 4 + 10

    2x = 4 + 10

    Combine like terms: 4 + 10 = 14

    2x = 14

    Divide each side by ‘2’.

    x = 7

    Simplifying

    x = 7
