<span>|x+ 1/2| =3 2/3
1) x+1/2=3 2/3
x=3 2/3 - 1/2
x=3 4/6 -3/6
x=3 1/6 (first root)
2) -(</span>x+1/2)=3 2/3
<span> - x- 1/2 = 3 2/3
- x =3 2/3 + 1/2
-x= 3 4/6 + 3/6
-x = 3 7/6 =3+1+1/6
-x=4 1/6
x= - 4 1/6

Answer:
7 < x < 9
Step-by-step explanation:
x^2 – 16x + 63 < 0
this is a parabola that opens up.
The parabola will be < 0 for values between the roots.
to picture this see the graph below.
Factor
(x - 7)(x - 9) < 0
Roots
x = {7, 9}
solution
7 < x < 9
