Question

Can somebody please help me with elimination?
Please show and explain your work.
3x-3y=18 and 5x+4y=12

Please only explain and show your work. I will not take people just giving me answers. I like to think for myself. I rather not cheat myself out of knowledge. I like to LEARN. Please help!! I will medal/fan.

Also, there are people who gave me answers, confused me with not doing the problem correctly, and didn't answer my questions. Please DO NOT be this kind of person!! Thanks. :))


Anybody is welcome to help me learn, I appreciate all help. Thanks all! :)

Answer 1

Note: This is not for a test/quiz/grade but rather a practice problem I will be writing in my notebook for future reference and studying. I like to write the problems and work down as we go, so please allow a few seconds for that.

Answer 2

elimination
substitution
graphing
matrices
which one is easy for you ?

Answer 3

Elimination. That is what the problem says to do.

Answer 4

lol didn't see that sorry about that
alright
in order to eliminate we should get same terms with opposite sign
multiply first equation 5 and 2nd equation by -3
or multiply first equation by -5 and 2nd one with 3
doesn't matter we need same terms with opposite sign
