Himpunan penyelesaian dari sistem 2x-3y=8 dan x 2y=-3 adalah

Penjelasan dengan langkah-langkah:

mungkin maksudnya;

2x - 3y = 8

x + 2y = -3

Metode substitusi

2x - 3y = 8 –> 2x - 3y = 8

x + 2y = -3 –> x = -3 - 2y

2x - 3y = 8

2(-3 - 2y) - 3y = 8

2×(-3) - 2×2y - 3y = 8

-6 - 4y - 3y = 8

-6 - 7y = 8

-7y = 8 + 6

-7y = 14

y = -2

x = -3 - 2y

x = -3 - 2(-2)

x = -3 - (-4)

x = 1

HP = {1 , -2}
