Question 490046: 3x+y=4-3x
2y=x+9
I can figure the problem out all the way until I have the fraction on the side with y. How do I move the fraction to the other side of the equation to solve for y? I know this is simple but for some reason I just can't seem to figure it out. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! 6 x + 1 y = 4 .............1
-1 x + 2 y = 9 .............2
Eliminate y
multiply (1)by -2
Multiply (2) by 1
-12 x -2 y = -8
-1 x 2 y = 9
Add the two equations
-13 x = 1
/ -13
x =- 1/13
plug value of x in (1)
6 x + 1 y = 4
-0.46 + 1 y = 4
1 y = 4 + 0.46
1 y = 4.46
y = 40/9
