rearrange the equation of 2x-y=6 into terms of y first.

  • anonymous
so y=-2x+6?

  • anonymous
y=2x+6

2x-y=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) 2x-6=y y=2x-6

ok
anonymous
  • anonymous
now, solve both equations
anonymous
  • anonymous
1) y=2x-6 2) y=-3x+19

tell me what you get for the x value afterwards.

  • anonymous
how though?

do you know how to solve for both equations?

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

yes

1) y=2x-6 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.

y-y= 0 2x--3x becomes 2x+3x=5x -6-19=-25 0=5x-25 5x-25=0 5x=25 x=25/5 x=5
