Diketahui sistem persamaan linear

Jawaban:

nilai x + 3y = 5

Penjelasan dengan langkah-langkah:

Sistem persamaan linear

2x + 3y = 4 |×2| 4x + 6y = 8

3x + 2y = 1 |×3| 9x + 6y = 3 _

-5x = 5

x = 5/-5

x = -1

2x + 3y = 4

2(-1) + 3y = 4

-2 + 3y = 4

3y = 4 + 2

3y = 6

y = 6/3

y = 2

x = -1 ; y = 2

nilai x + 3y = -1 + 3(2)

= -1 + 6

= 5

Semoga Membantuu:)
