[tex] \frac{7}{b + 5} = \frac{10}{5} \\ [/tex]

[tex] \frac{7}{b + 5} = 2 \\ [/tex]

Multiply the sides of the equation by ( b + 5 ) :

[tex]7 =2 \times (b + 5)[/tex]

[tex]7 = 2b + 10[/tex]

Subtract the sides of the equation minus 10 :

[tex]7 - 10 = 2b[/tex]

[tex] - 3 = 2b[/tex]

Divided the sides of the equation by 2 :

[tex]b = - \frac{3}{2} \\ [/tex]
