Answer 1

Materi : SPLDV

Soal Nomor 1

x + 3y = 15

3x + 6y = 30

Eliminasi ( x )

3x + 9y = 45

3x + 6y = 30

__________-

3y = 15

y = 5

--

x = 15 - 3y

x = 15 - 15

x = 0

HP = { x,y } = { 0,5 } [ a. ]

Soal Nomor 2

3a + 5b = 16

4a + b = 10

Eliminasi ( a )

12a + 20b = 64

12a + 3b = 30

____________-

17b = 34

b = 34/17

b = 2

---

4a = 10 - b

4a = 10 - 2

4a = 8

a = 8/4

a = 2

HP = { x,y } = { a,b } = { 2,2 } [ b. ]

Semoga bisa membantu
