#k=-3/10#

Explanation:

#"collect like terms on left side of equation"#

#rArr-20k-6=0#

#"add 6 to both sides"#

#-20kcancel(-6)cancel(+6)=0+6#

#rArr-20k=6#

#"divide both sides by - 20"#

#(cancel(-20) k)/cancel(-20)=6/(-20#

#rArrk=-3/10#

#color(blue)"As a check"#

Substitute this value into the left side of the equation and if equal to the right side then it is the solution"

#(-9xx-3/10)-(11xx-3/10)-6=27/10+33/10-60/10=0#

#rArrk=-3/10" is the solution"#
