    (-3)(2x+4)=5(x-3)

    -6x - 12 = 5x - 15

    -11x = -3

    hope no more explanation is needed.

    (-3)(2x+4) = 5(x-3)
    -6x-12 = 5x - 15 (Multify and remove brackets)
    -6x-5x = -15 +12 (Transfer of sides of like factors changes sign)
    -11x = -3
    x = 3 / 11 (Transfer of number and multiplication by -1)
