The answer should be the first one, 2. Do you need and explanation?
4x+y/2y-x

Start by replacing all of the variables. 
4(2)+4/2(4)-2

Now work multiply. 
8+4/8-2

Now add. 
12/6

That is your fraction. But you must simplify it. 

Its simplifies to 2.

Find the value of the variable
Neporo4naja [7]

Answer:

x=6

Step-by-step explanation:

I would look at this triangle and notice that x can be solved by setting up a ratio.

I generally put the short side of the triangle on the top and the long side on the bottom

4/x = x/9

You then cross multiply to get 36=x^2, or +-6=x

A length of a triangle cannot be negative, so we are left with the answer x=6
