Answer Step-by-step explanation:


\huge\boxed{b=-5}

Solve both sides of the equation.


-3+(-4)(-4)(-4)+(-4)(-b)=-4b+-27
(distribute)


-3+16+4b=-4b+-27


(4b)+(-3+16)=-4b-27
(combine~the~like~terms)


4b+13=-4b-27

Add 4b to both the sides.


4b+13+4b=-4b-27+4b


8b+13=-27

Subtract 13 from both the sides.


8b+13-13=-27-13


8b=-40

Divide both sides by 8.


(8b)/(8)=(-40)/(8)


b=-5


Answer~is~b=-5

Answer:

b=-5

Explanation:

  • Step 1: Simplify both sides of the equation.

−3−4(−4−b)=−4b−27

−3+(−4)(−4)+(−4)(−b)=−4b −2

(Distribute)

−3+16+4b=−4b+−27

(4b)+(−3+16)=−4b−27

(Combine Like Terms)

4b+13=−4b−27

4b+13=−4b−27

  • Step 2: Add 4b to both sides.

4b+13+4b=−4b−27+4b

8b+13=−27

  • Step 3: Subtract 13 from both sides.

8b+13−13=−27−13

8b=−40

  • Step 4: Divide both sides by 8.

8b/8 =−40/8

b=−5
