3x-2xb-1=x\left(2-3b-b\right)
Use the distributive property to multiply x by 3-2b.
3x-2xb-1=x\left(2-4b\right)
Combine -3b and -b to get -4b.
3x-2xb-1=2x-4xb
Use the distributive property to multiply x by 2-4b.
3x-2xb-1+4xb=2x
Add 4xb to both sides.
3x+2xb-1=2x
Combine -2xb and 4xb to get 2xb.
2xb-1=2x-3x
Subtract 3x from both sides.
2xb-1=-x
Combine 2x and -3x to get -x.
2xb=-x+1
Add 1 to both sides.
2xb=1-x
The equation is in standard form.
\frac{2xb}{2x}=\frac{1-x}{2x}
Divide both sides by 2x.
b=\frac{1-x}{2x}
Dividing by 2x undoes the multiplication by 2x.
b=-\frac{1}{2}+\frac{1}{2x}
Divide -x+1 by 2x.
3x-2xb-1=x\left(2-3b-b\right)
Use the distributive property to multiply x by 3-2b.
3x-2xb-1=x\left(2-4b\right)
Combine -3b and -b to get -4b.
3x-2xb-1=2x-4xb
Use the distributive property to multiply x by 2-4b.
3x-2xb-1-2x=-4xb
Subtract 2x from both sides.
x-2xb-1=-4xb
Combine 3x and -2x to get x.
x-2xb-1+4xb=0
Add 4xb to both sides.
x+2xb-1=0
Combine -2xb and 4xb to get 2xb.
x+2xb=1
Add 1 to both sides. Anything plus zero gives itself.
\left(1+2b\right)x=1
Combine all terms containing x.
\left(2b+1\right)x=1
The equation is in standard form.
\frac{\left(2b+1\right)x}{2b+1}=\frac{1}{2b+1}
Divide both sides by 1+2b.
x=\frac{1}{2b+1}
Dividing by 1+2b undoes the multiplication by 1+2b.
