There is No solution
1) Let's solve this Linear System of Equations by the Elimination Method:
18x +14y = 29
-9x-7y =-17 x2
18x +14y = 29
-18x -14y = -34
------------------------
0x -0y = -5
2) Hence, as we can see there is no Solution for this system since the 1st equation is a multiple of the 2nd one.
3) Hence, the answer is No solution
