Question

Obtain the general solution of the following equations:

1. Dx+(D−1)y = 5
2(D+1)x+(D+1)y = 0
​

Answer 1

To obtain the general solution of the given equations, use the method of elimination to eliminate the y term and solve for x. Substitute the value of x back into one of the equations to find the value of y.

Step-by-step explanation:

To obtain the general solution of the given equations, we can use the method of elimination. By multiplying the first equation by 2 and the second equation by -1, we can eliminate the y term when we add the two equations together. This will result in a linear equation with only the x term, which we can solve for x.

Once we have the value of x, we can substitute it back into either of the original equations to find the value of y. This will give us the general solution for the system of equations.
