#color(red)(=> -[7x+60]/10=-[{7x-60}/10]#

#[4.6x-3]+[-5.3x+9]#

#=>4.6x-3-5.3x+9#

#=>-0.7x+6#

#=-(7x)/10+6#

#=> -(7x)/10+60/10#

#color(red)(=> -[7x+60]/10=-[{7x-60}/10]#

~Hope this helps! :)

#-0.7x+6#

#+4.6x-3#
#ul(-5.3x+9larr" Add")#

Lets split the #-5.3# into #-4.6-0.7#. However this is counting #x's# so we can now write the above as:

#+4.6xcolor(white)("dddd.d")-3#
#ul(-4.6x-0.7x+9 larr" Add")#
#color(white)("ddd")0color(white)("d")-0.7x+6#

The final answer is: #-0.7x+6#
