Question

I need help on 3 questions-42 - 6n = -30

Answer 1

hello

the question given is an equation -42 - 6n = -30

step 1

collect like terms

`\begin{gathered} -42-6n=-30 \\ -42+30=6n \\ 6n=-12 \end{gathered}`

step 2

divide both sides by the coefficient of n

`\begin{gathered} 6n=-12 \\ (6n)/(6)=-(12)/(6) \\ n=-2 \end{gathered}`

from the calculations above, the value of n is equal to -2
