Answer:
x = 3
y = 1
Step-by-step explanation:
<u><em>The equations are:</em></u>

and

Putting second equation in the first one:
=> 
Subtracting 27 to both sides
=> 
=> 
Taking power 7 to both sides
=> y = 1
Now,

Taking cube root on the both sides
x = 3
(-23,-11) is the other endpoint due to (a+b/2)
X=-1
-1x2 + 5x-1 +7 = 0
-7+7 =0
0=0
Answer:
(-4,-2)
Step-by-step explanation:
The first one because it passes the through the origin
