Explanation:
#"multiply both sides by "-6#
#cancel(-6)xx(a-15)/cancel(-6)=-6xx-11#
#rArra-15=66#
#"add 15 to both sides"#
#acancel(-15)cancel(+15)=66+15#
#rArra=81#
#color(blue)"As a check"# Substitute this value into the left side of the equation and if equal to the right then it is the solution.
#(81-15)/(-6)=66/(-6)=-11#
#rArra=81" is the solution"#
