Answer:
[tex]\begin{bmatrix}\mathrm{Solution:}\:&\:x<-1\quad \mathrm{or}\quad \:x>7\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-1\right)\cup \left(7,\:\infty \:\right)\end{bmatrix}[/tex]
Step-by-step explanation:
apply the rule of absolute values: it means that x - 3 < - 4 or x - 3 > 4
solve each one:
x - 3 < -4 , x < -1
x - 3 > 4, x > 7
combine both answer sets
