Step :- 1

let the lowest marks be x

Highest Marks = 86 ( Given )

Lowest Marks = 3x - 7

Step :- 2

According to the Question ,

Highest Marks Obtained by Student in her class is three times the lowest marks

3x - 7 = 86

⇒ 3x = 86 + 7

⇒ 3x = 93

⇒ $x = \frac{93}{3}$

⇒ x = 31

Therefore , the lowest Marks of the class is 31

Answer 2

$your \: answer$
Equation Formed = 3x - 7

Because values of lowest marks = x

So 3x - 7 = 86

$3x - 7 = 86$

$3x = 86 + 7 = 93$

$x = \frac{93}{3} = 31$

Hence lowest marks are 31
