Answer:

see below

Step-by-step explanation:

│ x + 8│- 5= 2

Add 5 to each side

│ x + 8│- 5+5= 2+5

│ x + 8│= 7

The absolute value has two solutions, a positive and a negative

x+8 = 7 x+8=-7

Subtract 8 from all sides

x+8-8 = 7-8 x+8-8 = -7-8

x = -1 x = -15

7x²=9+x
so
for
0=ax²+bx+c

$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$
so

7x²=9+x
mins 9 from both sides and minus x
7x²-1x-9=0
a=7
b=-1
c=-9

$x=\frac{-(-1)+/-\sqrt{(-1)^2-4(7)(-9)}}{2(7)}$
$x=\frac{1+/-\sqrt{(-1)^2+4(7)(9)}}{2(7)}$
so the 4th one
