(43+45+47+49)=184
They are all odd and they are in consecutive order (one after another)
If the equation 2(g - h) = b + 4 is solved for g. Then the value of g will be b/2 + h + 2.
<h3>What is the solution of the equation?</h3>
A combination of equations solution is a collection of values x, y, z, etc. that enable all of the calculations to true at the same time.
The equation is given below.
2(g - h) = b + 4
Then solve the equation for the value of g. Then we have
2(g - h) = b + 4
g - h = b/2 + 2
g = h + b/2 + 2
More about the solution of the equation link is given below.

Answer:
Step-by-step explanation:
Given
![6x_1-9x_2=8](https://tex.z-dn.net/?f=6x_1-9x_2%3D8)
![9x_1+kx_2=-1](https://tex.z-dn.net/?f=9x_1%2Bkx_2%3D-1)
The given system is
can be represented by
![\begin{bmatrix}6 &-9 \\ 9 & k\end{bmatrix}\begin{bmatrix}x_1\\ x_2\end{bmatrix}=\begin{bmatrix}8\\ -1\end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7D6%20%26-9%20%5C%5C%209%20%26%20k%5Cend%7Bbmatrix%7D%5Cbegin%7Bbmatrix%7Dx_1%5C%5C%20x_2%5Cend%7Bbmatrix%7D%3D%5Cbegin%7Bbmatrix%7D8%5C%5C%20-1%5Cend%7Bbmatrix%7D)
The given system is consistent when determinant of A is not equal to zero
![|A|](https://tex.z-dn.net/?f=%7CA%7C)
![|A|=6k-(-81)=6k+81](https://tex.z-dn.net/?f=%7CA%7C%3D6k-%28-81%29%3D6k%2B81)
![k\neq \frac{-27}{2}](https://tex.z-dn.net/?f=k%5Cneq%20%5Cfrac%7B-27%7D%7B2%7D)
i.e. system is consistent for all value of k except ![k=\frac{-27}{2}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B-27%7D%7B2%7D)
![R-\frac{-27}{2}](https://tex.z-dn.net/?f=R-%5Cfrac%7B-27%7D%7B2%7D)
Answer:
there both the same cuz 23 down 23 up
