a)2x-(34-2)=

b)-3x-(-a+5)=

c)a-(-2a+1)=

d)4a(3-2a)=

e)2x-5-(x-3)=

f)2y+6-(3y+5)=

g)(3x-6)0-(-2x+4)=

h)(-2y-5)-(-3y+3)=

i)(3-2x)-(2x-3)=

j)(2a-3b)-(3a+7b)=

Answer 1

2x-[34-2]=2x-34+2=2x-32
-3x-[-a+5]=-3x+a-5
a-[-2a+1]=a+2a-1=3a-1
4a[3-2a]=12a-8a^
2x-5-[x-3]=2x-5-x+3=x-2
2y+6-[3y+5]=2y+6-3y-5= -y+1
[3x-6]0-[-2x+4]=2x-4
[-2y-5]-[-3y+3]= -2y-5+3y-3=y-8
[3-2x]-[2x-3]=3-2x-2x+3= -4x+6
[2a-3b]-[3a+7b]=2a-3b-3a-7b= -a-10b

Answer 2

a)2x-34+2=2x-32

b)-3x+a-5

c)a+2a-1=3a-1

d)12a-8a2

e)2x-5-x+3=x-2

f)2y+6-3y-5=-y+1

g)3x-6+2x-4=5x-10

h)-2y-5+3y-3=y-8

i)3-2x-2x+3=-4x+6

j)2a-3b-3a-7b=-a-10b
