The absolute value of a number is the distance of that number from zero on the number line. Therefore, the equation
means that the distance of
from zero is 10. This can happen in two cases:Case 1:
In this case, we subtract 5 from both sides of the equation to solve for
:
Case 2:
In this case, we subtract 5 from both sides of the equation to solve for
:
Therefore, the solution set for the equation
is
.The correct answer is
.
