Answer:

b = - 1

Step-by-step explanation:

given the equation

7b - [tex]\frac{2}{5}[/tex] = 6b - [tex]\frac{7}{5}[/tex] ( multiply through by 5 to clear the fractions )

35b - 2 = 30b - 7 ( subtract 30b from both sides )

5b - 2 = - 7 ( add 2 to both sides )

5b = - 5 ( divide both sides by 5 )

b = - 1
