Solve each system by elimination

What is the x-value of the solution to this system of equations?

25x + 50y = -4

10x + 20y = 0

Respuesta :

Answer:

No solution

Step-by-step explanation:

Let's eliminate y, since we want the value of x.

Multiply the second equation by (-5/2).  The result is:

-25x - 50y = 0

Combining this result with the first equation, we see that both x and y "disappear" and have the end result 0 = -4.  This is never true, so

This system has no solution.
