Answer :
[tex]\text {Hello! To find n you must...}[/tex]
[tex]\text {Flip the Equation:}[/tex]
[tex]\text {Before: -8=n-9}\\\text {After: n-9=-8}[/tex]
[tex]\text {Note: You need to flip the equation to solve n and what it equals to.}[/tex]
[tex]\text {The Final Step is to add 9:}[/tex]
[tex]\text {n-9+9=-8+9}[/tex]
[tex]\text {Your answer will be}[/tex]
[tex]\fbox {n=1}[/tex]
[tex]\text {Note: Instead of subtracting 9 we add 9 so they can cancel out.}[/tex] [tex]\text { We are finding n so we need it to cancel out.}[/tex]
[tex]\text {Best of Luck!}[/tex]
