3x-5y-4=0&9x=2y+7 now tell me ...​

Answer»

Answer:D

3x-5y=4....... equation 1

9x=2y+7= 9x-2y=7...... equation 2

Now by elimination method .

Equation 1... (3x-5y=4 ) ×3

9x-15y=12..... Equation 3

(We need to ELIMINATE one coordinate so we MADE x of 1st equation equal tothe 2nd )

So now by elimination method.

9x-15y=12

9x- 2y=7

(-). (+). (-)

-13 y =+ 5

y=-5/13

From eq 1

3x -5(-5/13)=4

x= 9/13

Therefore

x=9/13

y=-5/13.

If you find my answer CORRECT PLEASE MARK me as the brainliest......
