Well..I'm guessing you would do this.
2x+3y=6 -2x -2x 3y=6-2x /3 /3 y= 2-2/3x You want to get Y alone, so first you'd subtract 2x and you'd do the same for the other side. Then you divide by 3 to get the Y variable by itself and you get the ending result. I'm sorry if I'm a little vague. You would do the same with the others. At least that's what I think. |
