Question

Form the pair of linear equations for the following problems and find their solution by substitution method

The difference between two numbers is 26 and one number is three times the other. Find them.

 

Solution

Let larger number = x

Smaller number = y

The difference between two numbers is 26

x – y = 26

x = 26 + y

Given that one number is three times the other

So x = 3y

Putting the value of x we get

26y = 3y

-2y = - 2 6

y = 13

So value of x = 3y

Putting value of y, we get

x = 3 × 13 = 39

Hence the numbers are 13 and 39.

  Is there an error in this question or solution?
