3x - y + 5
Step-by-step explanation:
4x - 3y + 10 - x + 2y - 5
To simplify, you need to combine like terms. Like terms are terms that have the same variable part. All terms with x are like terms and can be combined. All terms with y are like terms and can be combined. All terms with no variable are like terms and can be combined. A term with x and a term with y are not like terms and cannot be combined.
It may be helpful at first, to move the like terms together to combine them.
4x - 3y + 10 - x + 2y - 5 =
= 4x - x - 3y + 2y + 10 - 5
= 3x - y + 5
Ответ:
3 x − y + 5
