Answer:
[tex]b=\frac{14}{5}[/tex]
[tex]b=2.8[/tex]
Step-by-step explanation:
[tex]2b+7+8b=35[/tex]
Combine like terms:
[tex]\longmapsto[/tex] [tex]2b+8b=10b[/tex]
[tex]\longmapsto 10b+7=35[/tex]
Subtract 7 from both sides:
[tex]\longmapsto10b+7-7=35-7[/tex]
[tex]\longmapsto10b=28[/tex]
Divide both sides by 10:
[tex]\longmapsto\frac{10b}{10}=\frac{28}{10}[/tex]
[tex]\longmapsto[/tex] [tex]b=\frac{14}{5}[/tex]
