Pair Of Linear Equations In Two Variables

Question 3:

Answer:

(i) Let the first number be x and the other number be y such that y > x.

According to the given information,

On substituting the value of y from equation (1) into equation (2), we obtain

Substituting this in equation (1), we obtain

y = 39

Hence, the numbers are 13 and 39.

(ii) Let the larger angle be x and smaller angle be y.

We know that the sum of the measures of angles of a supplementary pair is always 180º.

According to the given information,

From (1), we obtain

x = 180º − y (3)

Substituting this in equation (2), we obtain

Putting...
