#color(red)(y=-3#

#2y+3+4=5y+16#

#2y+7=5y+16#

By transposing method:

#2y-5y=16-7#

#-3y=9#

#y=9/-3#

#color(red)(y=-3#

~Hope this helps! :)

#y=-3#

#2y+3+4=5y+16#

Subtract #2y# from #2y# and #5y#

#3+4=3y+16#

Add #3# and #4# together

#7=3y+16#

Subtract #16# from #16# and #7#

#-9=3y#

Divide both sides by #3#

#y=-3#
