5(3b - 8) + 4 = -4 - b

b=2

Step-by-step explanation:

5(3b−8)+4=−4−b

Step 1: Simplify both sides of the equation.

5(3b−8)+4=−4−b

(5)(3b)+(5)(−8)+4=−4+−b (Distribute)

15b+−40+4=−4+−b

(15b)+(−40+4)=−b−4 (Combine Like Terms)

15b+−36=−b−4

15b−36=−b−4

Step 2: Add b to both sides.

15b−36+b=−b−4+b

16b−36=−4

Step 3: Add 36 to both sides.

16b−36+36=−4+36

16b=32

Step 4: Divide both sides by 16.

16b=32

b=2

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio
