See the entire solution process below:

Explanation:

Step 1) Add color(red)(14) to each side of the equation to isolate the B term while keeping the equation balanced:

-15B - 14 + color(red)(14) = -4 + color(red)(14)

-15B - 0 = 10

-15B = 10

Step 2) Divide each side of the equation by color(red)(-15) to solve for B while keeping the equation balanced:

(-15B)/color(red)(-15) = 10/color(red)(-15)

(color(red)(cancel(color(black)(-15)))B)/cancel(color(red)(-15)) = (5 xx 2)/color(red)(5 xx -3)

B = (color(red)(cancel(color(black)(5))) xx 2)/color(red)(cancel(5) xx -3)

B = -2/3
