x-3=21x-8-1
Combine 3x and -2x to get x.
x-3=21x-9
Subtract 1 from -8 to get -9.
x-3-21x=-9
Subtract 21x from both sides.
-20x-3=-9
Combine x and -21x to get -20x.
-20x=-9+3
Add 3 to both sides.
-20x=-6
Add -9 and 3 to get -6.
x=\frac{-6}{-20}
Divide both sides by -20.
x=\frac{3}{10}
Reduce the fraction \frac{-6}{-20} to lowest terms by extracting and canceling out -2.
