Solution set refers to all values that could make the equation hold true. For a linear equation, there's normally one value in its solution set. However, if the linear equation contains absolute value, they may be more than one solutions.
2x3 = 13
Remove absolute value sign by making the absolute value equals to both positive and negative values on righ hand side. Then, two linear equations are obtained.
2x3 = 13 or 2x3 = 13
Solving the two equations gives
x = 8 or x =5
Therefore,
The solution set of the equation is {5,8}
E is the correct answer.
