I need someone to tell me how to do these kinds of problems (In great detail please)

-5x=9-2x


-8x-10=4x+14

    -5x=9-2x

    We need to get the knowns on one side of the equation and the unknowns on the other side. Start by adding 2x to both sides of the equation.

    -5x + 2x = 9 - 2x + 2x
    -3x = 9
    x = 9/-3
    x = -3

    __________________________

    -8x-10=4x+14
    -8x - 4x = 14 + 10
    -12x = 24
    x = -2
