Question

4/x+3y=8;6x-4y=-5. I challenge everyone ​

Answer 1

Answer:

x=-2/9&y=17/3

Step-by-step explanation:

equation 1

4/x+3/y=8

=>4y+3x=8xy............equation 3 ×4

=>16y+12x=24xy

equation 2

6/x-4/y=5

=>6y+4x=5xy................equation 4. ×3

=>18y+12x=15xy

By subtracting equation 3&4

16y+12x=24xy

18y+12x=15xy

- - -

___________

-2y =9xy

=>-2=9xy/y

=>-2=9x

=>-2/9=x

therefore,substituting the value in equation 1,

4/-2/9+3y=8

=>-9+3y=8

=>3y=8+9

=>3y=17

=>y=17/3
