#0.37(28+62.7k)=56.758#
#color(white)("XXXX")##color(white)("XXXX")## rArr k = 2#

Explanation:

#0.37(28+62.7k)=56.758#

Distribute the multiplication on the left side:
#color(white)("XXXX")##(0.37)(28)+(0.37)(62.7k) = 56.758#

Subtract #(0.37)*(28)# from both sides:
#color(white)("XXXX")##(0.37)(62.7)k = 56.758 - (0.37)(28)#

Divide both sides by #(0.37)*(62.7)#
#color(white)("XXXX")##k = (56.758 - (0.37)(28))/((0.37)(62.7))#
