The diagram can be redrawn as,
The value of x and y can be determined as,
![\begin{gathered} \tan C=\frac{AB}{BC} \\ \tan 45^{\circ}=\frac{x}{7\sqrt[]{2}} \\ x=7\sqrt[]{2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctan%20C%3D%5Cfrac%7BAB%7D%7BBC%7D%20%5C%5C%20%5Ctan%2045%5E%7B%5Ccirc%7D%3D%5Cfrac%7Bx%7D%7B7%5Csqrt%5B%5D%7B2%7D%7D%20%5C%5C%20x%3D7%5Csqrt%5B%5D%7B2%7D%20%5Cend%7Bgathered%7D)

Thus, option (D) is the correct solution.
The equation has no solution.
<h3>How to solve the equation?</h3>
The equation given is illustrated as:
3x-2y=3 .... i
6x-4y=1 ..... ii
Multiply equation i by 6
Multiply equation ii by 3
18x - 12y = 18
18x - 12y = 3
Subtract the equations.
This will give 0. Therefore, the equations gas no solution.
