Question 156709
I'll do the first one to get you started


# 1




{{{4(n-3)=-16}}} Start with the given equation.



{{{4n-12=-16}}} Distribute.



{{{4n=-16+12}}} Add {{{12}}} to both sides.



{{{4n=-4}}} Combine like terms on the right side.



{{{n=(-4)/(4)}}} Divide both sides by {{{4}}} to isolate {{{n}}}.



{{{n=-1}}} Reduce.
