Need correct answer or I will report.
Need answer in explaination.​

Answer 1

Answer:

Given that,

A = x - 2y + z,

B = -2x + y + z

C = x + y - 2z

Step-by-step explanation:

According to the problem,

=> A+B-C

=>( x-2y+z)+(-2x+y+z)-(x+y-2z)

=> x-2x-x-2y+y-y+z+z+2z

=> -2x-2y+4z

Therefore ,A+B-C= -2x-2y+4z
