-(-1-x)=-2(3x-1)
We move all terms to the left:
-(-1-x)-(-2(3x-1))=0
We add all the numbers together, and all the variables
-(-1x-1)-(-2(3x-1))=0
We get rid of parentheses
1x-(-2(3x-1))+1=0
We calculate terms in parentheses: -(-2(3x-1)), so:We add all the numbers together, and all the variables
-2(3x-1)
We multiply parentheses
-6x+2
Back to the equation:
-(-6x+2)
x-(-6x+2)+1=0
We get rid of parentheses
x+6x-2+1=0
We add all the numbers together, and all the variables
7x-1=0
We move all terms containing x to the left, all other terms to the right
7x=1
x=1/7
x=1/7
