Question

sum of marks obtained by two students in an examination is 70 the marks secured by one student is 5 more than twice that of marks secured by the other write suitable linear equation

Answer 1

marks of first student,= X
marks of second student= 2x +5
so linear equation is
X +2x + 5=70

Answer 2

Answer:

$3x+5=70$

Step-by-step explanation:

Given :

Sum of marks obtained by two students in an examination is 70.

The marks secured by one student is 5 more than twice that of marks secured by the other  .

To Find: write suitable linear equation

Solution:

Let the marks obtained by one student be x

Since we are given that The marks secured by one student is 5 more than twice that of marks secured by the other  .

So, marks scored by other student = 2x+5

Since we are given that  Sum of marks obtained by two students in an examination is 70.

⇒$x+2x+5=70$

⇒$3x+5=70$

Hence suitable linear equation is $3x+5=70$
