We have such equation
5x-3y=12 /-5x (subtract 5x both sides)
5x-5x-3y=12-5x
-3y=-5x+12 /:3 divide both sides by 3
-y=
/*(-1) multiply both sides by -1
y=-
y=
- its the answer
5x-3y=12 /-5x (subtract 5x both sides)
5x-5x-3y=12-5x
-3y=-5x+12 /:3 divide both sides by 3
-y=
y=-
y=
I think you're factoring this...? You can do that by grouping here. Put the 4 terms in groups of 2 and factor out the greatest common factor. What's left behind is a common binomial factor that can also then be factored out. Like this:
Factoring what we can out of both sets gives us this:
The 2n-5 is a common factor between both the sets of terms, which in turn can also be factored out:
I'm not exactly sure what you are doing with this, but we can keep factoring for the sake of completeness. The 5 n-squared term can also be factored:
and 
and 
so 
. Simplifying that down its simplest is this:
So your three factors for that polynomial are
