Solve the system x 2y 9 5x 10y 45 SolutionIts inconsiste
     Solve the system.  {x + 2y = -9  5x + 10y = -45   
  
  Solution
It\'s inconsistent, it has no solution:
Solving for X first:
x + 2y = -9 ----> x = -9 - 2y
Now substituing in the second equation:
5(-9 - 2y) + 10y = -45
-45 - 10y + 10y = -45
-45 = -45
0 = 0
Therefore it does not have a solution
