Question

if 2x + 3y = 6 and ax + 6y = 8 are parallel then value of a.​

Answer 1

Answer:

if 2X + 3Y = 6 and ax + 6Y = 8 are only then value of a .

answers - value of a = 2

Answer 2

Step-by-step explanation:

2x+3y=6...............equation 1 ×2

=4x+6y=12

ax+6y=8...............equation2

therefore,

by subtracting equation 1&2

4x+6y=12

ax+6y=8

- - -

________________

4x-ax =4

=>x(4-a) =4

=>4-a=4/x

=>-a=4/x-4

=>-a=(4-4x)/x

=>a= -(4-4x)/x

=>a=(-4+4x)/x
