b)-a+1/3=4a-2

c)3x+(5-x)=6-(4x-1)

d)6(x-3)-2(3x-1)=3x

e)2x-[4-(x-3)]=9x

Answer 1

A)1/3+2x= -41+6x =-12/36x=-12-1/36x=-13/32x=-13x=-13/2

B)-a +1/3=4a-23(-a) +1=12a-6/3-3a-12a=-6-1/3-15a=-7/3-15a+7/3=-5a=-7 x(-1)A=7/5


C)3x +(5-x)= 6-(4x-1)3x+5-x=6-4x+13x-x+4x=6+1-52x+4x=7-56x=2x=2/6X=1/3


D)6(x-3)-2(3x-1)=3x6x-18-6x+2=3x6x-6x-3x=-2+18-3x=16 (-1)x=16/3=5,33...
