The denominators are already the same, so subtract the numerators and then simplify to get.

# ( 1- y)/ y #

# (9 -4y - ( 6 - y ))/(3y)#

#= (9 -4y - 6 + y )/(3y)#

#= (9 -6 - 4y + y )/(3y)#

#=(3 -3y)/(3y) #

#=( 3 - 3y)/ (3y)" "# Factor 3 out of the numerator

# =(3 ( 1-y ) )/(3 xx y)" "# The 3 in the numerator and the 3 in the #color(white)(......................)#denominator can be cancelled, leaving

#= ( 1- y)/ y #
