please don't spam coz tomorrow is my test. The answer should be the.. it is given in the image. Please solve it step by step ​

Answer 1

Answer:

sum1=8x-5y-2z+(-6x+8y-4z)

        =(8x-6x)+(-5y+8y)+(-2z-4z)

        =2x+3y-6z

sum2=6x+2y-4z+(-2x+4y-8z)

        =(6x-2x)+(2y+4y)+(-4z-8z)

        =4x+6y-12z

result=sum2-sum1

        =4x+6y-12z-(2x+3y-6z)

        =4x+6y-12z-2x-3y+6z

        =(4x-2x)+(6y-3y)+(-12z+6z)

        =2x+3y-6z
