Answer:

#k=12#

Explanation:

#"multiply both sides by 2 to eliminate the fraction"#

#cancel(2)xx3/cancel(2)k=2xx18#

#rArr3k=36#

#"divide both sides by 3"#

#(cancel(3) k)/cancel(3)=36/3#

#rArrk=12#

#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.

#"left "=3/cancel(2)^1xxcancel(12)^6=3xx6=18=" right"#

#rArrk=12" is the solution"#
