substitute.
anonymous
  • anonymous
just need the steps
Plasmataco
  • Plasmataco
replace the bottem equations with Y on the top equation.
Plasmataco
  • Plasmataco
add X^2 and subtract 4 from both sides to get X^2+2x-3
anonymous
  • anonymous
alright got that
Plasmataco
  • Plasmataco
the simplify to get (X-1)(X+3)
Plasmataco
  • Plasmataco
X can be either 1 or -3.
Plasmataco
  • Plasmataco
now, sub it in.

  • anonymous
x^2 + 3x -x -3
Plasmataco
  • Plasmataco
yup
Plasmataco
  • Plasmataco
you got it.
anonymous
  • anonymous
so that's the answer?
Plasmataco
  • Plasmataco
no.
Plasmataco
  • Plasmataco
simplify it to (X-1)(X+3)
Plasmataco
  • Plasmataco
then, for (X-1)(X+3)=0, X could be 1 or negative 3.

  • anonymous
x^2 + 3x -x - 3 x^2 + 2x -3
Plasmataco
  • Plasmataco
sub it in so Y=2X+1, X=1, Y=3. (1,3) when X=-3 Y=5 so (-3,5)
Plasmataco
  • Plasmataco
nononono
Plasmataco
  • Plasmataco
don't multiply both of them.
Plasmataco
  • Plasmataco
make separate equations like X-1=0 and X+3=0
Plasmataco
  • Plasmataco
then, look up to see the rest.

  • Plasmataco
I'm 13 XD

  • anonymous
nice
Plasmataco
  • Plasmataco
well, get it?
