Question

2 upon x + 2 upon 3 y is equal to 1 upon 3 is to 3 upon x + 2 y is equal to zero write the solution in linear equation by elimination method

Answer 1

2/x + 2/3y = 1/3

3/x + 2y. = 0

let, 1/x = u and 1/y = v

so,

2u + 6v = 1/3 – eq 1 * 3

3u + 2v = 0 – eq 2 * 2

6u + 18 v = 1

6u + 4 v = 0

solving this equation

so, v = 0

putting the value of v

2u + 6v = 1/3

2u = 1/3

u = 1/6

so, 1/x = u

1/x = 1/6

x. = 6

and 1/y = v

1/y = 0

y = 0

so, x = 6 , y = 0
