<em>Answer and Step-by-step explanation:</em>

<em>\Huge \boxed{b=-1}.</em>

<em>Step 1 : Simplify both the sides of the equation :</em>

<em>7b-37=4(5b-6)\\7b+-37=(4)(5b)+(4)(-6)\\7b+-37=20b+-24\\7b-37=20b-24</em>

<em>Step 2 : Subtract 20b from both sides :</em>

<em>7b-37-20b=20b-24-20b\\-13b-37=-24</em>

<em>Step 3 : Add 37 to both sides :</em>

<em>-13b-37+37=-24+37\\-13b=13</em>

<em>Step 4 : Divide both sides by -13 :</em>

<em>\frac{-13b}{-13}=\frac{13}{-13}</em>

<em>b=-1</em>

<em />

<em>That's our final answer !</em>

Step-by-step explanation:

1) 7b – 37 = 4(5b - 6)

7b - 37= 20b - 24

-13b = 13

dividing both sides by -13

b=-13/13=-1

<h3> b = -1</h3>
