Answer:

9y-y-7y+3= y+3

Step-by-step explanation:

Any time there is no number in front of a variable, it's automatically 1, you just don't put the 1 there. So it would be

9y - 1y= 8y

So after you do that, you take the 7y and subtract it from 8y

8y - 7y= 1y

And remember you don't put the 1 so it simplifies to just y.

You simply add or subtract all the numbers with the same variable

I'm not the best at explaining so if you have any questions on it I can answer them in the comments :)
