Question

if the equation 2 X + 3 Y is equal to 9 and a x + Y is equal to 3 represent the same line then the value of 'a' is equal to​

Answer 1

given en 2x+3y =9

ax+y =3 reps same line

divide first eqn by 3

we get ( 2/3)x+(3/3)y= 9/3

simplify (2/3)x+ y =3

now compare with second eqn

a = 2/3
