What is 13y-2x-12-15y
What are you solving for? Are you solving for (y) or (x) or are you just combining "like" terms?
-2x-2y-12
Yea what mayah said. If you are combining "like terms"
To simplify the expression 13y - 2x - 12 - 15y, you can start by combining like terms.
First, combine the terms with the variable 'y'. In this case, you have 13y and -15y, so you can simplify them by subtracting:
13y - 15y = -2y
Next, you have the term -2x. Since it doesn't have any like terms to combine with, it remains as is:
-2x
Finally, you have the constant terms -12. When combining constant terms, you simply add or subtract them:
-12
Now, we can put all the simplified terms together:
-2y - 2x - 12
So, the simplified form of the expression 13y - 2x - 12 - 15y is -2y - 2x - 12.
