Here's the Solution to this Question
We shall use the following well-known properties of congruences:
1) if then
2) if and then
Let us solve the linear congruence This congruence is equivalent to that is Since we conclude that after dividing both parts by 2 the last congruence is equivalent to Then we have and hence Taking into account that we conclude that that after dividing both parts by the solution of the congruence is
