2\times 7b-3b=20b-8
Multiply both sides of the equation by 4, the least common multiple of 2,4.
14b-3b=20b-8
Multiply 2 and 7 to get 14.
11b=20b-8
Combine 14b and -3b to get 11b.
11b-20b=-8
Subtract 20b from both sides.
-9b=-8
Combine 11b and -20b to get -9b.
b=\frac{-8}{-9}
Divide both sides by -9.
b=\frac{8}{9}
Fraction \frac{-8}{-9} can be simplified to \frac{8}{9} by removing the negative sign from both the numerator and the denominator.
