Answer:
x=-4.73 x=-1.27
Step-by-step explanation:
(x + 3)^2 - 3 = 0
Add 3 to each side
(x + 3)^2 - 3 +3= 0+3
(x + 3)^2 = 3
Take the square root of each side
sqrt((x + 3)^2) =±sqrt( 3)
(x + 3) =±sqrt( 3)
Subtract 3 from each side
x + 3-3 =-3±sqrt( 3)
x = -3±sqrt( 3)
Approximating to 2 decimal places
x=-1.27 x=-4.73
1/3 of 154.35 is 51.45
$51.45 will be saved on the jacket with it's regular price.
154.35 - 51.45 = 102.90
The sale price of the jacket will be 102.90 .
Hope I was able to help!

AM I WRONG?
Answer:
y = 4
x = -16
Step-by-step explanation:
this time we should multiply the first equation with -1 because we only need to change its state of negativity
2x + y = -28
-2x - 2y = 24 ➡ -y = -4 ➡ y = 4
if 2x + y = -28 the 2x + 4 =-28 ➡ 2x = -32 x = -16
