​

Answer 1

Answer:

3x+2y-5z+2x-5y+2z

5x-3y-3z

5x-3(y+z)

Answer 2

Given,

The two expressions: 3x+2y-5z and 2x-5y+2z.

To find,

The value after adding 3x+2y-5z and 2x-5y+2z.

Solution,

The value after adding 3x+2y-5z and 2x-5y+2z will be 5x-3y-3z.

We can easily solve this problem by following the given steps.

According to the question,

We have to add 3x+2y-5z and 2x-5y+2z.

(3x+2y-5z) + (2x-5y+2z)

We know that the numbers with the same variables are added or subtracted.

(3x+2x) + (2y-5y) + (-5z+2z)

5x-3y-3z

(Note that if two terms are of different signs then they are subtracted but the sign is used of the greater term.)

Hence, the value after adding 3x+2y-5z and 2x-5y+2z is 5x-3y-3z.
