Answer:
x = -5, 5
Step-by-step explanation:
-x^2-8=-33
Add 8 to each side
-x^2-8+8=-33+8
-x^2 = -25
Divide each side by -1
x^2 = 25
Take the square root of each side
sqrt(x^2) = ±sqrt(25)
x = ±5

Answer:
no solutions
Step-by-step explanation:
x + 2y = 1
y = − 1/ 2 x + 4
Substitute the second equation into the first
x + 2(-1/2x+4) = 1
Distribute
x -x +8 = 1
Combine like terms
8=1
This is never true so there are no solutions
