Explain why the addition method might be preferred over the substitution method for solving the system 2x-3y=5 5x+2y=6

Am not understanding this. Could someone please explain to me. If x^2+bx+c is factorable and c is negative, then the signs of the last term factors of the binomials are opposite, why? If x^2+bc+c is factorable and c is positive, then the signs of the last...

If x is 10, is 2/x in proportion to x/50? Why I am not understanding the question very well. Algebra is not easy for me.

Thank you this does help. But why is the addition method preferred over the substitution method for solving the system 2x-3y=5 5x+2y=6 I got how you got the 19x=38 but whatis the x=2(sorry not good with algebra)

Thank you...
