#y=-6#

#12(5+2y)=4y-(6-9y)#

#=> 60+24y=4y-6+9y#

#=> 60+24y=13y-6#

#=> 24y-13y=-60-6#

#=> 11y=-66#

#=> y=-66/11#

#=> y=-6#

#y = -6#

#12(5 + 2y) = 4y - (6 - 9y)#

#60 + 24y = 4y - 6 + 9y#

#60 + 24y = 13y - 6#

#24y - 13y = - 6 - 60#

#11y = - 66#

#(11y)/11 = - 66/11#

#(cancel11y)/cancel11 = - 66/11#

#y = -6#
