Question

the highest marks obtained by a student is thrice the lowest marks plus 9 find the lowest score in the highest score is 84​

Answer 1

Answer:

Lowest marks = x

Highest marks= 3x+9

Answer 2

Answer:

Let the lowest score be x.

According to the question,

3x + 9 = 84

→ 3x = 84 - 9 (Transposing + 9 to R.H.S.)

→ 3x = 75

→ 3x/3 = 75/3 (Dividing both sides by 3)

→ x = 25

Hence, the lowest score is 25.
