What is the x if 9l5x-3l = 90

Given the equation:

9 l 5x-3
l = 90

We need to solve for
x.

First, we need to isolate the absolute value on the left
side by itself.

Then, we will divide by 9 both
sides.

==> l 5x-3 l =
10

Now we have two
cases:

Case(1): (5x-3) =
10

==> 5x =
13

==> x= 13/5

Case(2):
-(5x-3) = 10

==> -5x +3 =
10

==> -5x =
7

==> x = -7/5

Then, we
have two answers:

x = -7/5 and
x=13/5
