Question

3x+2y=12, x-y+1=0 please sahi answer dena​

Answer 1

Answer:

$3x + 2y = 12 - - - - - (1)\\ x - y + 1 = 0 \\ > x - y = - 1- - - - (2) \\ multiply \: the \: 2nd \: equation \: by \: 2 \\ 2x - 2y = - 2 - - (3) \\ now \: (1) + (3) \\ 3x + 2y = 12 \\ 2x - 2y = - 2$

_______________________________

$5x = 10 \\ x = \frac{10}{5} \\ x = 2 \\ putting \: x = 2 \: in \: equation \: 2 \\ 2 - y = - 1 \\ y = 3$

x=2,y=3.

Hope it helps
