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......
