Answer:

y=-17

Step-by-step explanation:

3y+20=3+2y

Start by subtracting 20 from each side...

3y+20-20=3+2y-20\\3y=2y-17

Now, subtract "2y" from each side...

3y-2y=2y-2y-17\\y=-17

Next, let's substitute -17 for y in the original equation to check our answer...

3(-17)+20=3+2(-17)\\-51+20=3+(-34)\\-31=3-34\\-31=-31\rightarrow Correct!

Therefore the answer is:

y=-17
