Question

1.- (3x + 2y - 1) + (6y - 4x + 1)
2.-(x+y+7)-(3y-4x-1)
3.(10b+5bc-6c)+(7bc-4b+c)-(9c-8bc)
4.*(8xy-2yz)+(2xy-z+6yz)+(9yz*7yx-3z)
5.-(5ab-2a+b)+(ab+2a-3)+(5a-ab)

Answer 1

(3x+2y-1) + (6y-4x+1)

3x+2y-1+6y-4x+1

3x-4x+2y+6y-1+1

-1x+8y

(x+y+7)-(3y-4x-1)

x+y+7-3y+4x+1

x+4x+y-3y+7+1

5x-2y+8

(10b+5bc-6c)+(7bc-4b+c)-(9c-8bc)

10b+5bc-6c+7bc-4b+c-9c+8bc

10b-4b+5bc+7bc+8bc-6c+c-9c

6b+20bc-14c

(8xy-2yz)+(2xy-z+6yz)+(9yz*7yx-3z)

8xy-2yz+2xy-z+6yz+9yz*7yx-3z

8xy+2xy-2yz+6yz+9yz*7yx-3z

10xy+13yz*7yx-3z

(5ab-2a+b)+(ab+2a-3)+(5a-ab)

5ab-2a+b+ab+2a-3+5a-ab

5ab+ab-ab-2a+2a+5a+b-3

5ab+5a+b-3

(espero ayudarte! :) )
