Jawaban

[tex]x + 3y = 4[/tex]

[tex]x = 4 - 3y[/tex]

[tex]3x - 2y = 1[/tex]

[tex]3(4 - 3y) - 2y = 1[/tex]

[tex] 12 - 9y - 2y = 1[/tex]

[tex]12 - ( - 11y)= 1[/tex]

[tex] - 11y = 1 - 12[/tex]

[tex] - 11y = - 11[/tex]

[tex]{ \bold{y = 1}}[/tex]

[tex]x + 3y = 4[/tex]

[tex]x + 3(1) = 4[/tex]

[tex]x + 3 = 4[/tex]

[tex]x = 4 - 3[/tex]

[tex]{ \bold{x = 1}}[/tex]
