Question 454259
.
use substitution method to determine whether the system of linear equations has no solution, one solution,or many solutions

2x - y = 8
x + 4y = 13
~~~~~~~~~~~~~~~~~~~~~



For some reason, @josgarithmetic showed up here and once again brought his wrong solution, stating that y = 9.


He shows up at the forum almost every time as I post my correct solution - and every time he tries to corrupt it.


I don't know how he's tolerated on this forum.


For other visitors - my advice is to ignore his posts, for the peace in your mind.


About him,  everybody should know three truths: 


        (a)   @josgarithmetic does not know  Math,


        (b)   can not solve  Math problems correctly,


        (c)   can not teach  Math.
