sorry #1 is = 3 not +3

You can't solve without a common denominator.
24x/24 - 30/24 - 4x/24 = 16/24
20x/24 = 46/24
20x = 46
x = 46/20 = 2.3

All these are about finding the least common denominator. Learn that and you will get the answers.
take the first one
x/3 + 2x/5 = 3 (probably copied incorrectly)
multiple both sides by 15 (3 x 5)
5x + 6x = 45
11x = 45
x = 45 /11

Is the first equation a typo (X/3+X2/5=3) or does it equal zero? All of the other ones have an equals sign.

1) = (11x / 15) + 3
haven't got time to do any more.

it will be quicker for you to start than sit and wait for someone to answer you and you will learn more.
