Homework Statement
Solve in [tex]K=\mathbb{Z}/_{5}\mathbb{Z}\cdot\mathbb{Z}/_{5}\mathbb{Z}[/tex] the following system of equations:
[tex]\begin{cases}
2^{-}x-3^{-}y=1^{-} & 1^{-}x+2^{-}y=2^{-}\end{cases}[/tex]
Not that the ^- means a number with a bar over it. ( I don't know how to input it in the latex software that I use.
The Attempt at a Solution
I solve this system of equations by using the second equation to get x=2-2y and i substituted it for x in the first equation and i got a solution of S={(-6^-,4^-)}
Is that solution correct??
