Final Answer:

The solution for the variable b is b = -a + 7/3. None of the given options is answer.

Step-by-step explanation:

In the process of solving the equation 5b - 6a - 7 = 2b - 9a and expressing the result in terms of b, the final solution is b = -a + 7/3. This involves rearranging the equation, combining like terms, and step-by-step isolation of b. The ultimate expression for b showcases a systematic simplification, providing confidence in the correctness of the derived solution.

Given is:

5b - 6a – 7 = 2b - 9a

Move all the b terms on one side of the equation:

5b - 2b = -9a + 6a + 7

3b = -3a + 7

Divide both sides by 3 to isolate b:

b = (-3a + 7) / 3

Simplify the equation:

b = -a + 7/3

Therefore, the solution is b = -a + 7/3.

None of the given options is answer.
