Question

pasangan bilangan (x, y) yang memenuhi sistem persamaan diatas adalah.....​

Answer 1

Materi : SPLDV

Persamaan 1

1/( x + y ) - 2/( 2x - 3y ) = - 5/14

( x + y ) - ( 2x - 3y )/2 = - 14/5

2x + 2y - ( 2x - 3y ) = - 28/5

- y = -28/5

y = 28/5

Persamaan 2

1/( x + y ) - 1/( 2x - 3y ) = 11/28

x + y - 2x + 3y = 28/11

- x + 4y = 28/11

x = 4y - 28/11

x = 112/5 - 28/11

x = ( 1.232 - 140 )/55

x = 1.092/55

Semoga bisa membantu

Answer 2

Jawaban:

• Persamaan ke-1

1/( x + y ) - 2/( 2x - 3y ) = - 5/14

( x + y ) - ( 2x - 3y )/2 = - 14/5

2x + 2y - ( 2x - 3y ) = - 28/5

- y = -28/5

y = 28/5

• persamaan ke-2

1/( x + y ) - 1/( 2x - 3y ) = 11/28

x + y - 2x + 3y = 28/11

- x + 4y = 28/11

x = 4y - 28/11

x = 112/5 - 28/11

x = ( 1.232 - 140 )/55

x = 1.092/55
