Answer:

{-8, 8}

Explanation:

Simplify 7· |n| = 56 by dividing both sides by 7:

|n| = 8

Because this is an absolute value equation, there are two separate solutions. One is n = +8 and the other is n = -8.

There are two solutions.


</p><p>7*\mid n\mid=56\Longrightarrow\mid7n\mid=56 \\</p><p>\mid7* x_1\mid=56\Longrightarrow x_1=(56)/(7)=\boxed{8} \\</p><p>\mid7*(-x_1)\mid=56\Longrightarrow-x_2=(56)/(7)\Longrightarrow x_2=\boxed{-8}</p><p>
