Help with these would be much appreciated. Thanks!

Solve the equation graphically.

|4x-3| = 5√(x+4)

(4x-3) = 5√(x+4)

4x= 5√(x+4) + 3

x = (5√(x+4) + 3)/4??

-4x+3=5√(x+4)

x=(5√(x+4) -3)/-4

Ok, assuming I did the math correctly (feel free to correct), I am not sure how to "Solve Graphically."

Solve the inequality, express in interval notation.

|x-8|>4

x=12,

-x=-4 so x=4?

x=12,4 did I do this correctly??
