Question

Solve the equation. If there is no solution, write no solution. 4|n| – 19 = 13

A. n = 8 or n = –8
B. n = 28 or n = –36
C. no solution

Answer 1

A works if you substitute 8 in for 'n', however it doesn't if you put in -8. The answer should still be 8, because the absolute value of a number cannot be negative.

Hope this helps :)
