Question

how many solutions does the system of equations below have?
x - 10y = 9
2x - 20y = 18
no solution
one solution
infinitely many solutions

Explanation:

Step1: Simplificar la segunda ecuación

Divide la segunda ecuación entre 2:
$\frac{2x - 20y}{2} = \frac{18}{2}$
$x - 10y = 9$

Step2: Comparar las dos ecuaciones

La primera ecuación es $x - 10y = 9$, y la segunda, al simplificar, es idéntica a la primera. Esto significa que ambas representan la misma recta.

Answer:

infinitely many solutions
