Start by expanding the brackets "2(x+4)". Then, start collecting similar terms (those that have "x" with each other, and those that dont have "x" go together). Finally, your answer should be "3x + 5 - 2x - 8 + 3" which is equal to just x.
5x7=35
5x7=5x(5+2)
5x7=(5x3)+(5x4)
5x7=20+15
5x7=35
This is how I would do it :)
The plotted point will be reflected across the y-axis.
I belive there is none because it lands on the origin for y.
Given expression is

Now we need to simplify this expression. We can begin by factoring numerator and denominator if possible.

divide numerator and denominator both by 2v


Hence final answer is 
Or you can also keep factored form
