Question

Solve : 3/x - 2/y = 0 and
2/x + 5/y = 19 .
Hence, Find 'a' if y = ax + 3.
Give the right answer.​ plz

Answer 1

Answer:

-16/3

Step-by-step explanation:

take 1/x as u and 1/y as v

∴the equations will be

3u-2v=0 and 2u + 5v=19

these can be written as

6u-4v=0 and 6u +15v=57

subtracting second equation by the first,

we get

19v=57

∴v=3

∴y=1/3

∴u=2

∴x=1/2

since y=ax+3

∴a=y-3/x

    =(1/3 -3)/1/2

    =-16/3
