Answer:

x = -3, -10

Explanation:

|2x+13| - 1 = 6

|2x+13| = 7

2x + 13 = ± 7

Let's solve

2x + 13 = 7

2x = -6

x = -3

2x + 13 = -7

2x = -20

x = -10

So, x = -3, -10

We can start solving this equation by isolating the absolute value expression on one side of the equation:

|2x+13| - 1 = 6

|2x+13| = 7

Next, we can split this equation into two separate cases, depending on whether 2x+13 is positive or negative. If it's positive, we can drop the absolute value bars, and if it's negative, we need to flip the sign inside the absolute value bars:

2x + 13 = 7 or -(2x + 13) = 7

Solving the first equation, we get:

2x = -6

x = -3

Solving the second equation, we get:

-2x - 13 = 7

-2x = 20

x = -10

Therefore, the solution set for the equation |2x+13|-1=6 is { -10 , -3 }.
