tentukan penyelesaian dari SPL berikut x + 3y = 11 2x - 5y = -11

x + 3y =>> 11 [ ×2 ]
2x + 5y =>> -11

[>> 2x + 3y =>> 22
[>> 2x + 5y =>> -11
________________ -
=>> -8y =>> 11
=>> y =>> - 11/8

2x + 3y =>> 22
2x + - 33/8 =>> 22
2x =>> 22 - - 33/8
2x =>> 22+33/8
2x =>> 26,125
x =>> 13,0625

[tex]x + 3y = 11 \: \: ( \times 2) \\ 2x - 5y = - 11 \\ \\ 2x + 6y = 22 \\ 2x - 5y = - 11 \\ itu \: dikurang \: jadinya \: 11y = 33. \: y = 3 \\ \\ x + 3y = 11 \\ x+ 3(3) = 11 \\ x + 9 = 11 \\ x = 2[/tex]
Maaf kalo salah:)
