there are so many ways of doing this problem! you can solve for x or y. let's solve for x. take -4x+y=41 when u solve x= 1/4y-41/4 plug that value of x into the other equation: 6x+3y=-21 it should look like this 6(1/4y-41/4)+3y=-21 and solve for y after u...

each letter can be written in many ways just use the # of arrangements

use long or synthetic division.

you can also use the process of elimination so : 2x=8 when u add them, x=4 and plug it in to whatever equation. come on, that's too easy!

that's easy..but i don't wanna answer them lol
