See a solution process below:

Explanation:

First, add #color(red)(4.8k)# to each side of the equation to isolate the #k# term while keeping the equation balanced:

#7.14 - 4.8k + color(red)(4.8k) = 19k + color(red)(4.8k)#

#7.14 - 0 = 23.8k#

#7.14 = 23.8k#

Now, divide each side of the equation by #color(red)(23.8)# to solve for #k# while keeping the equation balanced:

#7.14/color(red)(23.8) = (23.8k)/color(red)(23.8)#

#0.3 = (color(red)(cancel(color(black)(23.8)))k)/cancel(color(red)(23.8))#

#0.3 = k#

#k = 0.3#
