Question

Use the elimination method to solve the given system of equations.
5x +y=3
10x +2y=4
a.(0,3)
b.(0,10)
c.no solutions
d.infinitely many solutions

kropot72 · Answer

If (5x + y = 3) is multiplied by 2 on both sides it becomes 10x + 2y = 6. But the second equation says 10x + 2y = 4. Therefore there can be no solutions.

Thanks Again :)

jhonyy9 · Answer

multiply first by -2 and assum those 

5x+y=3  *(-2)
-10x -2y =-6
 10x +2y =4
--------------
   0     0  =-2

- so than result that the system have not solutions
