Question 1189287: −2x+2y=−4
3x+3y=−18
​
I got help on this but the tutor just gave me articles that did not make much sense to me. If you could, could I have a quick step-by-step explanation on how to do this problem?

-2x%2B2y=-4......eq.1
3x%2B3y=-18...........eq.2
--------------------------------------
you have linear system to solve
first, simplify
-2x%2B2y=-4......eq.1.......... both sides divide by 2
3x%2B3y=-18...........eq.2,, both sides divide by 3
-----------------------------
-x%2By=-2......eq.1
x%2By=-6...........eq.2
--------------------------------add both
-x%2By%2Bx%2By=-2-6
2y=-8
y=-4
go to

x%2By=-6...........eq.2, substitute y=-4
x-4=-6
x=-6%2B4
x=-2
solution:
x+=+-2, y+=+-4

This is not a problem.
It's 2 equations.
====
A problem might be: solve for x and y.

Hello,  you just got confused with your numerous posts.

Meanwhile,  I track them very attentively.

The current system  (of this your post)   was just  SOLVED  for you in full   by tutor @MathLover1.


The tutor,  who gave you links to articles  IN  OTHER  YOUR  POST  and  for another system,  is  ME.


After getting your comment,  I produced the full solution for you,
in your very first post under this link

Track attentively your posts and do not panic . . .

You wrote that my lessons did nit make much sense for you.

Meanwhile,  in my lessons,  I explained at a very introductory level,  how to solve such systems using the basic methods.


If these lessons do not make sense for you,  it may happen in two cases, only:

        (a)   if you do not want  (or do not able)  stretch your mind to learn the subject,   or

        (b)   if you do not want to learn the subject,  at all,  and only want to obtain ready solutions,
              written by others,  in order for copy-paste them and to sign/(to send) them later as if they are produced by you.


              In any case,  there is nothing to be proud of,  if you can not understand clearly written text.

        It is strange to me to see such a "student" . . .
