Each one has it's own steps, try tackling them individually and asking questions in places you get stuck.
When you have a fraction getting a common denominator is the first step.
On problem 1 combining ur x's to one side and whole numbers to the others is first steps.
When there is a whole number times whatever in () timesing is first for example 6(x-3) is 6x-18 then do steps that you did in question 1.
