    you need to learn a few things like shapes and parallel lines and then angle theories

    any line traversing parallel lines will result congruent angles and I've used a's and b's to show their relationships

    only if you want to do proofs perhaps, but in this case it is not necessary you just need to extract information from a line traversing a parallel line and expand from it

    here's what you can try, solve for x and see if that will give you the correct answer

    let us start with a very simple arithmetic \(2 + 3 = x \)

    okay then let us try this \(2+y = 5 \) solve for y

    subtract 2 from 5

    \(2 \color{red}{-2} + y = 5 \color{red}{-2} \)

    in essence you just didn't subtract two from five, you subtracted two on both sides

    \(2x+4 = 12 \) if you wanted to solve for x, you first isolate the variable x, and in order to do that is like doing the reverse of how you end up with 2x you will effectively subtract 4 on both sides and then make 2x into 2 by dividing both sides with two.

    in the last equation I gave you, yes.
