Encik Faizal bercadang membeli _x_ batang pen dengan harga RM6 sebatang dan sebuah buku berharga RM10

Jawab:

i. 6x + 10 = 52

ii. x 4 2/3

Penjelasan dengan langkah-langkah:

i. 6x + 10 = 52

6x = 42

x = 7

ii. 6x + 10 = 38

6x = 28

x = 4 2/3

Jawab:

(i) 6p + 10 = 52

(ii) the number of pens = 5

Penjelasan dengan langkah-langkah:

I'm bad at Malaysian; I'd rather speak in English because most of the Malays are indeed fluent speakers.

Given that

–> Each pen costs 6 Ringgits.

p = pen

Therefore the algebraic expression would be

6p

–> A book costs 10 Ringgits

b = book

Therefore the algebraic expression would be

b = 10

–> The total amount of money paid, is 52 Ringgits.

(i) Determine the linear equation for the aforementioned problem.

6p + b = 52

Therefore

6p + 10 = 52 <– answer

6p = 52 – 10

6p = 42

p = 42/6

p = 7

He will have to pay 52 Ringgits for 7 pens and a book

—————

(ii) Determine the number of pens if he buys a book and pays 38 Ringgits

The suitable algebraic expression for the aforementioned problem would be:

6p + 10 = 38

Solve for p (the number of pens – bought alongside the book – if he pays 38 Ringgits)

6p = 38 – 10

6p = 28

p = 28/6

p = 4,66

Rounded to the nearest unit, the number of pens = 5 <– answer
