Answer 1

(2-3)-(7-2)+4=-2

(-1)-(5)+4=-2

-1-5+4=-2

-6+4=-2

-2=-2

-(5-71)+(2-22)+(8-9)= 45

-(-66)+(-20)+(-1)=45

66-20-1=45

46-1=45

45=45

(3x+2y)-(4x-5y)=

3x+2y-4x+5y=

-x+7y=

-(4m-2n)-(m-6n)-(m+n)=

-4m+2n-m+6n-m-n=

-6m+7n=

-[-(4a-3b)-(a-7b)+(8a+4b-5c)]=

-[-4a+3b-a+7b+8a+4b-5c]=

4a-3b+a-7b-8a-4b+5c=

-3a-14b+5c=

3x-[-(x-y)+(4x-5y)]=

3x-[-x+y+4x-5y]=

3x+x-y-4x+5y=

4y=

2a-{2a-[(5a-b)-(a-b)]}=

2a-{2a-[5a-b-a+b]}=

2a-{2a-5a+b+a-b}=

2a-2a+5a-b-a+b=

4a=

(3x+2y)-(4x-5y)=

3x+2y-4x+5y=

-x+7y=

-(-3x+4)+(-3x-5)=

3x-4-3x-5=

-9=

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

-{4m-2n-[m-n+m-n]}+6m=

-{4m-2n-m+n-m+n}+6m=

-4m+2n+m-n+m-n+6m=

4m=
