mohon bantuannya kk ;-;...​

Answer 1

Jawaban:

HP = {(3, 1)}

Penjelasan dengan langkah-langkah:

SPLDV

2x - 5y - 1 = 0

2x - 5y = 1

-3y + 4x - 9 = 0

4x - 3y = 9

Eliminasi x

2x - 5y = 1 |×2| 4x - 10y = 2

4x - 3y = 9 |×1| 4x - 3y = 9

___________ -

-7y = -7

y = 1

Substitusi nilai y

2x - 5y = 1

2x - 5(1) = 1

2x - 5 = 1

2x = 6

x = 3

HP = {(3, 1)}
