 Question 380909: 3x-2y=9 -6x+4y=1 I need to solve special systems. (& if it is infinitely many, only one, or none. I tried to do substitution. Canceling out one variable I think the answer I got was x=6 and y=18. I am not sure it is right. I look at it and it just seems to long compared to the other problems. 3x-2y=9 -3 -3 x-2y=3 -x+x-2y=3+x -2y=3+x ---------- +2 +2 y =6+x 3x+y=6 3x+(6+x)=6 4x+6 =6 4x+6-6=6-6 4x = 0 Now it does not come out the way I had on paper. I did something wrong. Please help. Thank you. Click here to see answer by mananth(12270)
