Given:


5|x-3|+3>7

Aim:

We need to find the value of x.

Step-by-step explanation:

Subtract 3 from both sides of the equation.


5|x-3|+3-3>7-3


5|x-3|>4

Divide both sides of the equation by 5.


(5)/(5)|x-3|>(4)/(5)


|x-3|>(4)/(5)

Square both sides.


(x-3)^2>((4)/(5))^2


(x-3)^2>(16)/(25)


x^2-6x+9>(16)/(25)

multiply


x^2-6x+9>(16)/(25)
