#y = 4#

#17 = 5y - 3#

To solve for the variable #y#, we have to make it by itself.

First, add #color(blue)3# to both sides of the equation:
#17 quadcolor(blue)(+quad3) = 5y - 3 quadcolor(blue)(+quad3)#

#20 = 5y#

Now divide both sides by #color(blue)5#:
#20/color(blue)5 = (5y)/color(blue)5#

#4 = y#

Therefore, #y = 4#.

Hope this helps!
