Answer:
2 solutions:
x=5 and y=7
x=-1 and y=-5
Step-by-step explanation:
y=2x-3
y=x^2-2x-8
y=y so:
2x-3=x^2-2x-8
simplifying to:
x^2-4x-5=0
factoring to:
(x-5)(x+1)=0
x=5 or x=-1
if x=5 then y=2(5)-3=7
if x=-1 then y=2(-1)-3=-5

Answer:
Step-by-step explanation:
hello :
the system is : x+y+z=-6.....(1)
x-y+3z=-18.....(2)
2x+2y+2z=-8.....(3)
use (3): 2(x+y+z) = - 8 so : x+y+z = -4
use (1) : x+y +z = -6 -6=-4 false
no solutions
