Question

X+y=-9 -1x-2y=-5 Solve using substitution PLEASE

Answer 1

I think your answers are:
$y = - x - 9$
$y = - \frac{x}{3} + \frac{five}{two}$
My keyboard doesn't really work, my phone is cracked and I have, and I keep getting it wet, soo that's why I had to put 5 / 2 by smelling it out.

Answer 2

Y = -x - 9

-x -2(-x-9)=-5

-x +2x + 18 = -5
x + 18= -5
x= -23
-23+ y = -9
y= 14
