Answer:
b < - [tex]\frac{3}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{7}[/tex] > b + [tex]\frac{5}{7}[/tex] ( multiply through by 7 to clear the fractions )
2 > 7b + 5 ( subtract 5 from both sides )
- 3 > 7b ( divide both sides by 7 )
- [tex]\frac{3}{7}[/tex] > b , then
b < - [tex]\frac{3}{7}[/tex]
