solve 3y+6x+3=9+6x. Would you be so kind to help me solve this problem so that I can understand the steps? Thank you kindly.

3y + 6x + 3 = 9 + 6x

Subtract 6x from both sides
3y + 6x - 6x + 3 = 9 + 6x - 6x
3y + 3 = 9
Subtract 3 from both sides
3y + 3 - 3 = 9 - 3
3y = 6
Divide both sides by 3
3y/3 = 6/3
y = 2
