2xy=6 (bring the y to the right hand side so + y on both sides) and also (bring the six to the left hand side by 6 on both sides) 2x6=y y=2x6

okok, let me explain sonja, it's sonja right?

1) y=2x6 2) y=3x+19 we want to find the x value and to do this we have to get rid of the y value. Since we rearranged the first equation already in terms of y, we can directly solve for x now.
