Question

1) X=2y+5
3x-2y=19

2) X+5y=2
2x+3y=18

Answer 1

Respuesta:

$x - 2y = 5.......1$

$3x - 2y = 19.........2$

equation ...1and equation 2ed subtract

$x - 2y = 5 \\ 3x - 2y = 19$

$2x = 14$

$x = 7$

put the value of x

$x - 2y = 5 \\ 7 - 2y = 5 \\ - 2y = 2 \\ y = - 1$

2.

$2x + 10y = 4........1st \\ 2x + 3y = 18 \\ ......2nd \\ equation \: 1st \: ko \: second \: se \: hatane \: p \\ 7y = 14 \\ y = 2 \\ yki \: value \: equation \: 1st \: me \: rakhne \: per \: x + 10 = 2 \\ x = 2 - 10 \\ x = - 8$
