By arranging

#### Explanation:

$5 b - 5 \left(2 - 5 b\right) = - 5 \left(- 7 b - 2\right)$

First get rid of parantheses:

$5 b - 10 + 25 b = 35 b + 10$

Now collect terms (include b) on the left hand side and numbers on the other:

$30 b - 35 b = 10 + 10$

$- 5 b = 20$

$b = - \frac{20}{5} = - 4$

Your answer is $b = - 4$
