Answer 2

It seems like you have an equation involving the variable "b." The equation you provided is:

9 + 18b + 78 + 4b + 12 + 42b = 3.5

To solve this equation for "b," we need to simplify it and isolate the "b" term on one side of the equation. Let's proceed step by step:

1. Combine like terms: (18b + 4b + 42b) can be combined since they all have "b" as the variable. Summing them up, we get 64b.

2. Combine constants on the left side: (9 + 78 + 12) can be added together to give 99.

The equation becomes: 64b + 99 = 3.5

3. Isolate "b" on one side: To isolate "b," we need to get rid of the constant term on the left side. We can do this by subtracting 99 from both sides of the equation:

64b + 99 - 99 = 3.5 - 99

Simplifying:

64b = -95.5

4. Solve for "b": To find the value of "b," divide both sides of the equation by 64:

b = -95.5 / 64

b ≈ -1.4921875

So, the value of "b" in the given equation is approximately -1.4921875.
