Answer:
x = 6
y = - 14
Step-by-step explanation:
[tex]\left \{y=-2x2 + 10y} \atop {y=-2x -2}} \right.[/tex]
Answer:
Step-by-step explanation:
hello :
y = -2x² + 10
y = -2x – 2
-2x²+10 = -2x-2
2x²-2x -12 = 0
x²-x-6 = 0
(x-3)(x+2)=0
x-3=0 or x+2=0
x=3 or x=-2
but y = -2x-2
if ; x=3 y = -2(3)-2 =-8
if : x=-2 y=-2(-2)-2=2
two solutions : (3 , -8) and (-2 , 2)
