Question

3x + y = 1
- 4x + 12y = 28
3x - 4y = 2

For what value of k, the following pair of linear equations becomes consistent
7x-y=5; 21x-3y=k
Find the value of k for which the following equations are inconsistent
x - 4y = 6; 3x + ky = 5
drawing the graph, find out whether the lines representing​

Answer 1

Answer:

x-4y=6and3x+ky=5

k=-2

Step-by-step explanation:

• a1/a2=b1/b2 not equal to c1/c2
• 1/3=-4/k
• k=-12
