This site is for if you need help only. How the heck am I a nerd?

Who said I was giving up on math? There are just certain questions that I don't understand or just can't answer. And btw, I do online school, they don't give us books they only give us the material and videos that don't even go with the material.

First one:

The solutions to the system are the points where the two lines intersect. Since they don't intersect at any points, there is no solution.

Second one:

F - 32  =  $$\frac95$$(k - 273.15)                    We want to solve this equation for  k .

Multiply both sides of the equation by  $$\frac59$$

$$\frac59$$ * (F - 32)  =  $$\frac59$$ * $$\frac95$$(k - 273.15)

$$\frac59$$(F - 32)  =  k - 273.15

Add  273.15  to both sides of the equation.

$$\frac59$$(F - 32) + 273.15  =  k

k  =  $$\frac59$$(F - 32) + 273.15
