Reason (R): In the given equations, y can be substituted by `(1)/(p)`

A

Both (A) and (R) are true and (R) is correct explanation of the (A).

B

Both (A) and (R) are true but (R) is not the correct explanation of the (A).

C

(A) is true but (R) is false.

D

The correct Answer is:
To solve the problem, we need to analyze the given equations and the statements made in the assertion and reason. ### Given Equations: 1. \(\frac{2}{x} + 5y = 15\) 2. \(\frac{3}{x} + 6y = 7\) ### Step 1: Rewrite the Equations To analyze these equations, we can introduce a new variable for \(\frac{1}{x}\). Let's denote: \[ p = \frac{1}{x} \] Then we can rewrite the equations in terms of \(p\). ### Step 2: Substitute \(p\) into the Equations Now, substituting \(p\) into the equations: 1. The first equation becomes: \[ 2p + 5y = 15 \] 2. The second equation becomes: \[ 3p + 6y = 7 \] ### Step 3: Analyze the New Equations Now we have a new pair of equations: 1. \(2p + 5y = 15\) 2. \(3p + 6y = 7\) These equations are now linear in terms of the variables \(p\) and \(y\). ### Step 4: Check the Assertion and Reason - **Assertion (A)**: The given pair of equations can be reduced to a pair of linear equations in two variables. - This is **True** because we have successfully rewritten the equations in terms of \(p\) and \(y\), which are linear. - **Reason (R)**: In the given equations, \(y\) can be substituted by \(\frac{1}{p}\). - This is **False** because the substitution of \(y\) as \(\frac{1}{p}\) does not directly relate to the original equations. The equations are already linear in \(p\) and \(y\) without needing to express \(y\) in terms of \(p\). ### Conclusion The correct option that describes the statements is: - Assertion (A) is True. - Reason (R) is False.
