Step-by-step explanation:
Answer:
c
Step-by-step explanation:
Answer:
No solution
Step-by-step explanation:
So we have the equation:

First, subtract 20 from both sides:

Now, we can stop. Recall that absolute value will always <em>always</em> give a positive answer.
Since this equals -16, this means that there is no solution.
And we're done!
