 Question 135496: Instructions are to eliminate the denominator. {y=3/10x} I multiplied both sides by 10 and got: 10y=3x I chose 3 points for x, 10, 0, -10. I came up with order pairs (10,3)(0,0)(-10,-3) Not sure if this is right, nor if I worked the problem correctly using the correct formula. Click here to see answer by cbcrawford978(7)

 Question 135533: When I move the varible x to the other side and I divide the 12 and -x by negative 6, I am confused. x-6y=12. I get -6y=12-x. I know that to isolate y I need to divide the -6 by all terms. But I don't understand the -x over -6 Click here to see answer by vleith(2825)
