Step-by-step explanation:
Ok but where is the question

6y+4=8+2y+2y
Combine like terms
6y+4=8+4y
Get like terms on the same side, subtract 4 from both sides to get
6y=4+4y
Subtract 4y from both sides to get
2y=4 IS the answer (even though it can be simplified further, that answer isn't one of the choices so 2y=4 is the equation simplified.)

Step 2 was the mistake when you distribute a number you don't add (which is what they did to get 5x) you multiply to get 6x. So the correct step 2 would be
6x-8=12+2x
Becuase of the distributive property.
Hope this helped!
