helpppp!1 2/b+7+8b=35

Sagot :

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]
