Solve for x and y respectively 3x – 5y = 9 6x – 4y =…

Solve for x and y respectively
3x – 5y = 9
6x – 4y = 12
  • A.
    (frac{3}{4}), 1
  • B.
    (frac{4}{3}), 1
  • C.
    (frac{3}{4}), -1
  • D.
    (frac{4}{3}), -1
Correct Answer: Option D
Explanation

3x – 5y = 9 —x2
6x – 4y = 12 —x1
6x – 10y = 18
-6x – 4y = 12
___
(frac{6y}{-6}) = (frac{6}{6})
y = -1
in eq (1) 3x – 5y = 9
3x – 5(-1) = 9
3x + 5 = 9
3x = 4
x = (frac{4}{3})
