Question

17xy+21x-13xy-45x+5xy=???

Answer 1

17xy+21x-13xy-45x+5xy=9xy-24x ( это максимальное сокращение)

Answer 2

I can help you with your math problem. To simplify the expression 17xy+21x-13xy-45x+5xy, you need to do the following steps:

- Combine the like terms that have the same variable and exponent. For example, 17xy, -13xy, and 5xy are like terms because they all have xy. Similarly, 21x and -45x are like terms because they both have x. - Add or subtract the coefficients of the like terms. For example, 17xy - 13xy + 5xy = (17 - 13 + 5)xy = 9xy. Similarly, 21x - 45x = (21 - 45)x = -24x. - Write the final expression by putting the terms in descending order of the exponent. For example, 9xy - 24x is the final expression because xy has a higher exponent than x.

Therefore, the answer is 9xy - 24x. You can check your answer by using an online algebra solver or [Mathway](https://www.mathway.com/algebra).
