Let's start by simplifying this nasty inequality.
There is something very important here, there is a rule, that when you multiply an inequality by a negative number (we are doing this to get rid of the negative signs) you "flip" the inequality sign.
As for graphing, we know that we have a < sign. That means that while x is less than 1, it cannot be equal to 1. This means that we would dotted line that shows the border of our inequality. This should suffice: https://www.desmos.com/calculator/fkzvmzvg9t

OK, you have these two fractions. Now we find the Least Common Denominator (LCD) which in this case is 16. To produce an equilivant faction with a denominator of 16, we need to change the numerator in proportion to the denominator. To produce 16 from 4, we need to multiply by 4 (4*4=16) so we multiply the top numeber as well.
Ah! Now we have something we can easily work with.
We make sure that this fraction can't be simplified any further without making sub-fractions and decimals in fractions. It can't; therefore, this must be the answer.
Well according the order of operations, multiplication or division (left to right), then addition or subtraction (left to right).
I am assuming you mean this:
We have the multiplication, you start with that.
\(15 - 10\)
Then we have a simple subtraction problem
