hello
the question given is an equation -42 - 6n = -30
step 1
collect like terms
[tex]\begin{gathered} -42-6n=-30 \\ -42+30=6n \\ 6n=-12 \end{gathered}[/tex]step 2
divide both sides by the coefficient of n
[tex]\begin{gathered} 6n=-12 \\ \frac{6n}{6}=-\frac{12}{6} \\ n=-2 \end{gathered}[/tex]from the calculations above, the value of n is equal to -2
