Hope it helps you!!

Answer 2

Answer:

The second equation in a pair of the dependent equation can be x+y = 1

Step-by-step explanation:

Given,

One equation in a pair of linear equations is x+2y = 4

To find,

The second equation if the pair of equations are dependent.

Recall the concepts

A pair of linear equations  $a_1x+b_1y+c_1=0 \ and \ a_2x+b_2y+c_.2=0$ is consistent if $\frac{a_1}{a_2} \neq \frac{b_1}{b_2}$

Solution:

Since all consistent pairs of linear equations are dependent,

to get a dependent linear equation, we need to find a linear equation such that  $\frac{a_1}{a_2} \neq \frac{b_1}{b_2}$

here $a_1 = 1, b_1 = 2$

Let us take $a_2 = 1 , b_2 = 1, c_2 = 1$

Since   $\frac{a_1}{a_2} \neq \frac{b_1}{b_2}$the second equation which is dependent on the linear equation    x+2y=4  is x+y = 1

∴The second equation in a pair of the dependent equation can be x+y = 1
