Answer 1

Respuesta:

Explicación paso a paso:

1.

5y+2x-(y+5x+z)+(-2x+3y)+7z

5y+2x-y-5x-z-2x+3y+7z

2x-5x-2x+5y-y+3y-z+7z

-5x+7y+6z

2.

8a-[4b-11c+2-(3b+2c-7)+3a]

8a-[4b-11c+2-3b-2c+7+3a]

8a-[b-13c+9+3a]

8a-b+13c-9-3a

5a-b+13c-9

3.

-[5-(6xy-z)+2xy+7z+3]+5xy

-[5-6xy+z+2xy+7z+3]+5xy

-5+6xy-z-2xy-7z-3+5xy

-5-3+6xy-2xy+5xy-z-7z

-8+9xy-8z

4.

-(4x-3y+2)-[y+(1-x)+2y+3]

-4x+3y-2-y-1+x-2y-3

-4x+x+3y-2y-2-1-3

-3x+y-6

5.

{7-[-8y+3x-(-x-10y+3)-7x+2-3y]}

{7-[-8y+3x+x+10y-3-7x+2-3y]}

{7-[-8y+10y-3y+3x+x-7x-3+2]}

{7-[-y-3x-1]}

{7+y+3x+1}

3x+y+8

6.

-{x-5y-[2z-(7x-y+5)+6z]-3y}+2

-{x-5y-[2z-7x+y-5+6z]-3y}+2

-{x-5y-[8z-7x+y-5]-3y}+2

-{x-5y-8z+7x-y+5-3y}+2

-{x+7x-5y-y-3y-8z+5}+2

-{8x-9y-8z+5}+2

-8x+9y+8z-5+2

-8x+9y+8z-3

7.

5a-{3b-8c-[a+2c+6b-(b-c)-3a]-5c}

5a-{3b-8c-[a+2c+6b-b+c-3a]-5c}

5a-{3b-8c-[-2a+3c+5b]-5c}

5a-{3b-8c+2a-3c-5b-5c}

5a-{2a-2b-16c}

5a-2a+2b+16c

3a+2b+16c

8.

-{4m-[n-6-(2m-4n+2)+7n]-3m}

-{4m-[n-6-2m+4n-2+7n]-3m}

-{4m-[12n-8-2m]-3m}

-{4m-12n+8+2m-3m}

-{3m-12n+8}

-3m+12n-8
