See a solution process below:

Explanation:

First, subtract color(red)(7) from each side of the equation to isolate the b term while keeping the equation balanced:

-11b + 7 - color(red)(7) = 40 - color(red)(7)

-11b + 0 = 33

-11b = 33

Now, divide each side of the equation by color(red)(-11) to solve for b while keeping the equation balanced:

(-11b)/color(red)(-11) = 33/color(red)(-11)

(color(red)(cancel(color(black)(-11)))b)/cancel(color(red)(-11)) = -3

b = -3
