Simplify each term.
x−(9x−10)+11=12x−6x+1

Add 12x and −6x to get 6x.
x−(9x−10)+11=6x+1

Simplify each term.
x−9x+10+11=6x+1

Add x and −9x to get −8x.
−8x+10+11=6x+1

Add 10 and 11 to get 21.
−8x+21=6x+1

Move 6x to the left hand side of the equation by subtracting 6x from both sides.
−8x+21−6x=1

Add −8x and −6x to get −14x.
−14x+21=1

Move 21 to the right hand side of the equation by subtracting 21 from both sides.
−14x=−21+1

Add −21 and 1 to get −20.
−14x=−20

Divide each term in the equation by −14.
x=10/7

x is equal to 10/7 or 1 3/7
