Explain why the addition method might be preferred over the substitution method for solving the system
2x3y=5
5x+2y=6

bobpursley,
Two simple multiplications, and you can do it in your head.
multiply top equation by 2
4x6y=10
multiply the bottom equation by 3
15x+6y=18
add 19x=38
x=2

Amy L,
Thank you this does help. But why is the addition method preferred over the substitution method for solving the system
2x3y=5
5x+2y=6
I got how you got the 19x=38 but whatis the x=2(sorry not good with algebra)
