Question

Solve the equation. If there is no solution, select no solution. 5|n|-15=40

n = 11 or n = –11


n = 50 or n = –60


n = 11


no solution

Answer 1

n = 11 or n=-11

Explanation:

5|n|-15=40

Add 15 to each side

5|n|-15+15=40+15

5|n| = 55

Divide by 5

5/5 |n| = 55/5

|n| =11

The absolute value has a positive and a negative solution

n = 11 and n=-11
