Answer 1

Soalan

___________________________________________

3y + 4 = 8

3y = 8 - 4

3y = 4

y = 4/3

y = 1 1/3

___________________________________________

2x × 15 = 3

30x = 3

x = 3/30

x = 1/10

x = 0,1

Answer 2

Nomor 1

3y + 4 = 8

3y = 8 - 4

3y = 4

y = 4/3

Bukti:

3(4/3) + 4

= 4 + 4

= 8 ✅

Nomor 2

2x . 15 = 3

(2 . 15)x = 3

30x = 3

x = 3/30

x = (3 ÷ 3)/(30 ÷ 3)

x = 1/10

Bukti:

2(1/10) × 15

= 1/5 × 15

= 3 ✅
