    X = 13 because you have to add the x all to the left side than minus eleven from both sides which would equal - 2x=-26 then divide by - 2 which would equal x=13

    4x + 15 = 6x + - 11

    Reorder the terms:

    15 + 4x = 6x + - 11

    Reorder the terms:

    15 + 4x = - 11 + 6x

    Solving

    15 + 4x = - 11 + 6x

    Solving for variable 'x'.

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

    Add '-6x' to each side of the equation.

    15 + 4x + - 6x = - 11 + 6x + - 6x

    Combine like terms: 4x + - 6x = - 2x

    15 + - 2x = - 11 + 6x + - 6x

    Combine like terms: 6x + - 6x = 0

    15 + - 2x = - 11 + 0

    15 + - 2x = - 11

    Add '-15' to each side of the equation.

    15 + - 15 + - 2x = - 11 + - 15

    Combine like terms: 15 + - 15 = 0

    0 + - 2x = - 11 + - 15

    -2x = - 11 + - 15

    Combine like terms: - 11 + - 15 = - 26

    -2x = - 26

    Divide each side by '-2'.

    x = 13

    Simplifying

    x = 13
