Question

the solution X+Y=0& X-9Y=0 is​

Answer 1

Step-by-step explanation:

$x + y = 0 \\ \\ put \: x = 0 \\ 0 + y = 0 \\ y = 0 \\ \\ put \: x = - 1 \\ - 1 + y = 0 \\ y = 1 \\ \\ (0,0) \: \: ( - 1,1)$

,

$x - 9y = 0 \\ \\ put \: y = 0 \\ x - 9(0) = 0 \\ x - 0= 0 \\ x = 0 \\ \\ put \: y = 1 \\ x - 9(1) = 0 \\ x - 9 = 0 \\ x = 0 + 9 \\ x = 9 \\ \\ (0,0) \: \: (9,1)$
