Penjelasan dengan langkah-langkah:

x – 3y – 18 = 0

x – 3y = 18 . . . dikalikan 2

2x + 5y = 10

2x – 6y = 36

2x + 5y = 10 dikurangi

-11y = 26

y = -26/11

Atau y = -2 4/11 ⇔ y = $-2 frac{4}{11}$

2x + 5y = 10

2x + 5(-26/11) = 10

2x – 130/11 = 10

2x = 10 + 130/11

2x = (110 + 130) /11

2x = 240/11

x = 240/11 : 2

x = 240/11 x 1/2

x = 240/22

x = 10 20/22

x = 10 10/11 ⇔ x = $10frac{10}{11}$

b. titik potongnya ( $10frac{10}{11}$ , $-2 frac{4}{11}$ )
