Question

solve the following equation
3x-5y=7,5x+2y=3​

Answer 1

Answer:

3x-5y= 7 multiply this equation by 2

5x-2y=-1 multiply this equation by -5 & add.

6x-10y=14

-25x+10y=5

-------------

-19x=19

x=19/-19

x=-1 ans.

3*-1-5y=7

-3-5y=7

-5y=7+3

-5y=10

y=10/-5

y=-2

Proof:

5*-1-*-2=-1

-5+4=-1

-1=-1
