Tolong ya no 5 dan 6 belajar buat besok ^^

No. 5

tas = x

sepatu = y

Jika 2x = 5y, berarti 4x = 10y 

4x + y = 1,100,000

11y = 1,100,000

y =100,000

4x = 10y = 1,000,000

x = 1,000,000 : 4 = 250,000 

y = 100,000

3x + 2y = 3(250,000) + 2(100,000)

= 750,000 + 200,000 

= 950,000

No. 6

laptop = x

handphone = y

Jika 1x = 3y, berarti 2x = 6y

2x + 4y = 30,000,000

10y = 30,000,000

y = 3,000,000

x = 3y = 9,000,000

y = 3,000,000

3x + 5y = 3(9,000,000) + 5(3,000,000)

= 27,000,000 + 15,000,000

= 42,000,000

Semoga membantu ^3^
