#y= -3/5x +9/5#

Explanation:

First of all, I'm not sure why you posted this question in chemistry.
Anyway, firstly you subtract #3x# from both sides

#cancel(color(red)(-3x))+cancel(3x) +5y= 9 color(red)(-3x)#

to get

#5y = 9-3x#

Then you divide both sides by #5#

#cancel(5)y/(cancel(color(red)(5))) = (9-3x)/(color(red)(5))#

to get

#y = (9-3x)/5#

Distribute the #5# to each term

#y= 9/(color(red)(5))-(3x)/(color(red)(5)#

Rearrange (not necessary) to obtain the answer:

#y= -3/5x +9/5#
