#color(magenta)"k = -0.11111"#

#color(pink)("Subtract 3 on both sides:")#

#-9k+cancel3= 4#
#color(white)(aaa)-cancel3# #color(white)(a) -3#

3 cancels out on the left side, and when you subtract 3 from 4 on the right you get 1:

#-9k = 1#

#color(blue)("Divide both sides by -9 to get k by itself.")#

#(cancel"-9"k)/cancel"-9"=(1)/-9#

Now you are just left with #k# on the left side and -0.11111 on the right side.

Thus,
#color(magenta)"k = -0.11111"#
