Explanation:
#"using the "color(blue)"Intersecting chords theorem"#
#"When 2 chords intersect inside a circle, the product of"#
#"their segments are equal"#
#rArr18(n+1)=9(n+7)#
#"divide both sides by 9"#
#rArr2(n+1)=n+7#
#rArr2n+2=n+7#
#"subtract "n" from both sides"#
#2n-n+2=7#
#rArrn+2=7#
#"subtract 2 from both sides"#
#rArrn=7-2=5#
