Find the number of solutions of the following pair of linear equations :2x + 3y + 17 = 04x + 6x + 15 = 0​

Answer»

Answer:

4X + 6y + 15 = 0 ----------(ii)

and, 2x+3y+17=0 ---------------(i)

it can be seen of the cofficients of equations.

coe.of X of 1st coe. of y of 1st cons. term of 1st

-------------------- = --------------------- ≠ ------------------coe. of x of 2nd coff. of y of 2nd cons. term of 2

=> 2/4=3/6≠17/15

=> 1/2=1/2≠17/15

And this CONDITION for no SOLUTIONS or two

parallel lines.

So, the answer is no solution exist.
