{{{20y+5=9}}}


{{{20y+5-5=9-5}}} Subtract 5 from both sides


{{{20y=4}}} 


{{{20y/20=4/20}}} Divide both sides by 20


{{{y=4/20}}}


{{{y=(1*4)/(5*4)}}} Factor each part. This helps with reducing.


{{{y=(1*highlight(4))/(5*highlight(4))}}} We have a pair of 4 terms


{{{y=(1*cross(4))/(5*cross(4))}}} Those 4's cancel out


{{{y = 1/5}}} leaving us with this final answer
