Answer:
b = -12
Step-by-step explanation:
[tex] \dfrac{6 - 2b}{6} = 5 [/tex]
We are solving for b, so we want b alone on the left side equaling a number on the right side.
Start by multiplying both sides by 6.
[tex] 6 \times \dfrac{6 - 2b}{6} = 6 \times 5 [/tex]
[tex] 6 - 2b = 30 [/tex]
Now we subtract 6 from both sides.
[tex] 6 - 2b - 6 = 30 - 6 [/tex]
[tex] -2b = 24 [/tex]
Divide both sides by -2.
[tex] \dfrac{-2b}{-2} = \dfrac{24}{-2} [/tex]
[tex] b = -12 [/tex]
