    Simplifying

    6 (7n + - 5m) + 8m = 0

    Reorder the terms:

    6 (-5m + 7n) + 8m = 0

    (-5m * 6 + 7n * 6) + 8m = 0

    (-30m + 42n) + 8m = 0

    Reorder the terms:

    -30m + 8m + 42n = 0

    Combine like terms: - 30m + 8m = - 22m

    -22m + 42n = 0

    Solving

    -22m + 42n = 0

    Solving for variable 'm'.

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

    Add '-42n' to each side of the equation.

    -22m + 42n + - 42n = 0 + - 42n

    Combine like terms: 42n + - 42n = 0

    -22m + 0 = 0 + - 42n

    -22m = 0 + - 42n

    Remove the zero:

    -22m = - 42n

    Divide each side by '-22'.

    m = 1.909090909n

    Simplifying

    m = 1.909090909n
