Question

I need an anwser on 9y+6y-2 I already did it i just need to know if im doing it correct...

Answer 1

There is no equal sign in the problem, so this is just an algebraic expression.

9y+6y-2 is an algebraic expression because it has variables. A numerical expression doesn't have any variables, for example  3 minus 4 times 2 (3-4*2)

 

back to your problem...because it is an algebraic expression, you really cannot solve for y. All you can do is simplify.

So you must combine like terms......9y and 6y are like terms because they both have a y variable. So you would add them in this case. 9y + 6y = 15y

 

-2 is called a constant because there is no variable attached. You can combine other constants, but in this problem, there aren't other constants. so just attach it to the rest of the expression....15y -2

 

That's it!

Answer 2

The like terms are 9y and 6y. If you combine them, it becomes 15y. There is nothing you can do with -2. It does not have a y next to it. 

 

So, the answer is. 15y -2 or  15 y + (-2) 

 

There you have it.
