Answer:
[tex]y=-17[/tex]
Step-by-step explanation:
[tex]3y+20=3+2y[/tex]
Start by subtracting 20 from each side...
[tex]3y+20-20=3+2y-20\\3y=2y-17[/tex]
Now, subtract "2y" from each side...
[tex]3y-2y=2y-2y-17\\y=-17[/tex]
Next, let's substitute -17 for y in the original equation to check our answer...
[tex]3(-17)+20=3+2(-17)\\-51+20=3+(-34)\\-31=3-34\\-31=-31\rightarrow Correct![/tex]
Therefore the answer is:
[tex]y=-17[/tex]
