You can put this solution on YOUR website! I am giving guidance but not a solution.
First, isolate the absolute value expression and treat it as a variable to solve.
Next, examine two cases for the input of the absolute value FUNCTION, as the entire expression INSIDE the absolute value function.
Either 5x-3 is POSITIVE OR ZERO; meaning that  ;
OR
5x-3 is NEGATIVE; meaning  .
You can understand that second case if you would carefully examine according to the definition of absolute value and make reference to a number line.
Solve for both cases individually.
