Question

Do the equations 4x+3y-1=5 and 12x+9y=15 represent a pair of coincident lines. Justify your answer

Answer 1

Answer:

No

step by step explanation:

4x+3y-1=5 (1)

12x+9y=15 (2)

in (1) 4x+3y=5+1

4x+3y=6 (3)

balance is in the image.you should watch there.kkk

Answer 2

Answer:

4x + 3y - 1 = 5

4x + 3y = 5 + 1

4x + 3y = 6 ____(1)

12x + 9y = 15 ___(2)

a1/a2 = 4/12 , b1/b2 = 3/9 = 1/3, c1/c2 = 6/15 = 2/5

Here, a1/a2 = b1/b2 ≠ c1/c2

Hence, the pair of equation has no solution.
