Answer

Therefore, the solutions to the equation are \(\boxed{-\frac{3}{4}, \frac{9}{4}}\).

Steps

Step 1 :The absolute value equation can be solved by considering two cases: when the expression inside the absolute value is positive and when it is negative.

Step 2 :In the first case, we have \(3-4x - 1 = 5\), and in the second case, we have \(-(3-4x) - 1 = 5\).

Step 3 :We can solve these two equations separately to find the possible values of \(x\).

Step 4 :For the first equation, we get the solution \(-\frac{3}{4}\).

Step 5 :For the second equation, we get the solution \(\frac{9}{4}\).

Step 6 :We have two potential solutions for the equation, -3/4 and 9/4. However, we need to check if these solutions are valid by substituting them back into the original equation.

Step 7 :Both solutions, -3/4 and 9/4, are valid.

Step 8 :Therefore, the solutions to the equation are \(\boxed{-\frac{3}{4}, \frac{9}{4}}\).
