Question

Solve 30 sum plzz
I will mark u brainlist ok so plz solve

Answer 1

let 1/(2x+3y) =A, and 1/(3x-2y) =B,

then the equation becomes,

A/2 + 12B/7 = 1/2,

(7A+24B)/14 =1/2,

7A+24B=1/2 ×14,

then

7A+24B=7,........eq(1),

also

7A+4B=2,.............eq(2),

now subtract eq(2) from eq(1), we have

24B-4B=7-2,

20B=5,

B=5/20,

B=1/4,

but B=1/(3x-2y),

then

1/(3x-2y) =1/3,

3x-2y=3,.…..........eq(3),

now put the value of B in eq(2), we get

7A+4×1/4 =2,

7A+1=2,

then
7A=2-1=1,

then

A=1/7,

but

A=1/(2x+3y),

so

1/(2x+3y) =1/7,

2x+3y=7,.............eq(4),

so now on solving eq(3) and eq(4), u will get the values of x and y,

now i hope u can easily solved these two equations.....
