2x-2-3y+9=0 2x-3y=-7 3x+6-y+7=20 3x-y=7
Mertsj
  • Mertsj
So now we have: 2x-3y= -7 3x - y = 7

Let's take that second equation and solve it for y. We would get y=3x-7

Are you with me so far?

wouldn't it be -y = -3x + 7
anonymous
  • anonymous
oh wait.. y = -(-3x+7) = what u said yes go on
Mertsj
  • Mertsj
now multiply by -1 to get y
Mertsj
  • Mertsj
So let's take that value for y which is 3x-7 and put it in the first equation in place of y
Mertsj
  • Mertsj
2x-3y=-7 2x-3(3x-7)=-7

everything is clear till now

2x-9x+21=-7 -7x=-28 x=4 But y = 3x-7 y=3(4)-7 y=12-7 y=5 So the solution of the system is the ordered pair (4,5) and if you graphed the two equations you were given the lines would cross at (4,5)
