Answer:
The correct answer is 1 / 18.
Step-by-step explanation:
We are given the following equation for which we need to solve for the variable n:
[tex]-\frac{7}{3n} =-42[/tex]
So for solving this, we will rearrange the equation in a manner that isolates the variable n, making it the subject of the equation.
[tex]-\frac{7}{3n} =-42[/tex]
[tex]-\frac{7}{42} =3n[/tex]
[tex]\frac{1}{6} =3n[/tex]
[tex]n=\frac{1}{6*3} \\\\n=\frac{1}{18}[/tex]
Therefore, the value of n is equal to 1 / 18.
