Answer:
x=±15
Step-by-step explanation:
When we have absolute value equations, the first step is always to isolate the absolute value. This has already been done.
We know that a quantity in absolute value can be negative or positive, so in order to solve for it, we take the quantity inside the expression--in this case x--and set it equal to negative OR positive of the term on the right side. In this problem, this step would look like this:
[tex]x=-15[/tex] (the original right-side quantity)
and you would also need to solve for
[tex]x=15[/tex]
So [tex]x[/tex] can be ±15
