Nilai x dan y pada persamaan 3x + 2y =70 dan 2x + 3y = 80 adalah…


tolong jawab pake rumus lengkap yaa makasii <3!!​

Jawaban:

3x + 2y = 70

2x + 3y = 80

__________ _

x + -y = -10

x = -y – – 10

x = -y + 10

3x + 2y = 70

3(-y + 10) + 2y = 70

-3y + 30 + 2y = 70

-y = 70 – 30

-y = 40

y = -40

x = -y + 10

x = 40 + 10

x = 50
