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
