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
