Question

2x+y=10
x+2y=8
tentukan nilai x dan y​

Answer 1

Jawaban:

x = 4

y = 2

Penjelasan dengan langkah-langkah:

2x + y = 10

x + 2y = 8

..

2x + y = 10

y = 10 - 2x

..

x + 2(10 - 2x) = 8

x + 20 - 4x = 8

-3x = 8 - 20

-3x = -12

x = 4

..

2(4) + y = 10

8 + y = 10

y = 10 - 8

y = 2

..

HP = {4, 2}

Answer 2

Penjelasan dengan langkah-langkah:

2x+y=10|×1| 2x + y = 10

x+2y=8 |×2| 2x + 4y = 16

____________-

-3y = -6

y = 2

2x + y = 10

2x + 2 = 10

2x = 8

X = 4

HP = { X , y } { 4,2}
