Let's go through each of the questions one by one from the image you provided.

Question 1:

Given:

• First equation: $3x + 4y = -9$
• Second equation: $2x - 6y = 5$

We need to solve this system of equations to find the value of $b_2$.

Question 2:

Given:

• First equation: $4x - 3x = -9$
• Second equation: $2x - 5 = 6$

We need to find the value of $a_2$ by solving this system.

Question 3:

Given:

• First equation: $3x - 9y = 4$
• Second equation: $2x + 5y = 6$

We need to solve this system to determine the value of $c_1$.

Let me begin by solving the system of equations for each of the three questions. I'll show you the detailed steps.

I'll start with Question 1.For Question 1, solving the system of equations:

1. $3x + 4y = -9$
2. $2x - 6y = 5$

We get:

• $x = -\frac{17}{13}$
• $y = -\frac{33}{26}$

Thus, the value of $b_2$ (which seems to correspond to the solution for $y$) is $-\frac{33}{26}$.

Now, let's proceed to Question 2.It seems like I can’t do more advanced data analysis right now. Please try again later.

Would you like me to explain how to approach solving Question 2 manually, or answer any other part of the problem? Let me know!
