Directions: In the following questions, A statement of Assertion (A) ...
In case of assertion
View all questions of this test
x – 2y = 8 ...(i)
5x – 10 = c ...(ii)
As a1/a2 = b1/b2 , so system of linear equations can never have unique solution.
∴ Assertion is incorrect.
In case of reason:
The equation of one line is 4x + 3y = 14.
We know that if two lines a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0 are parallel, then
or
Hence, one of the possible, second parallel line is 12x + 9y = 5.
∴ Reason is correct Hence, assertion is incorrect but reason is correct.

Directions: In the following questions, A statement of Assertion (A) ...
Assertion: For all real values of c, the pair of equations x – 2y = 8 and 5x – 10y = c have a unique solution.
Reason: Two lines are given to be parallel. The equation of one of the lines is 4x + 3y = 14, 12x + 9y = 5.
To determine the correctness of the assertion and the reason, let's analyze each statement individually.
Statement A: For all real values of c, the pair of equations x – 2y = 8 and 5x – 10y = c have a unique solution.
To solve the system of equations, we can use the method of substitution or elimination. Let's use the method of substitution to find the solution.
From the first equation, x - 2y = 8, we can rewrite it as x = 2y + 8.
Substituting this value of x into the second equation, we get 5(2y + 8) - 10y = c.
Simplifying further, we have 10y + 40 - 10y = c.
The y terms cancel out, and we're left with 40 = c.
Since the value of c is fixed at 40 for any real value, the second equation becomes 5x - 10y = 40.
Therefore, the system of equations x - 2y = 8 and 5x - 10y = c always has a unique solution, which is x = 2y + 8.
Statement R: Two lines are given to be parallel. The equation of one of the lines is 4x + 3y = 14, 12x + 9y = 5.
To determine if two lines are parallel, we need to compare their slopes. If the slopes are equal, the lines are parallel.
The slope-intercept form of a linear equation is y = mx + b, where m is the slope.
Let's rewrite the given equations in slope-intercept form:
4x + 3y = 14
3y = -4x + 14
y = (-4/3)x + 14/3
12x + 9y = 5
9y = -12x + 5
y = (-12/9)x + 5/9
y = (-4/3)x + 5/9
Comparing the slopes of both equations, we can see that they are equal (-4/3).
Therefore, the given lines 4x + 3y = 14 and 12x + 9y = 5 are parallel.
Conclusion:
From the analysis above, we can conclude that both Assertion (A) and Reason (R) are true. However, Reason (R) does not provide the correct explanation for Assertion (A). The parallel lines mentioned in Reason (R) are not directly related to the given system of equations in Assertion (A).
