Answer: x = 9 / 14 & y = -7 / 3
Step-by-step explanation:
Take x-2y=3
Multiplying the equation by 2, we get
2x-4y=6
Now subtract 2nd equation from 1st equation
2x-4y=6
- 2x-y =-1
-----------------
-4y - (-y) = 6 - (-1)
-4y + y = 6 + 1
-3y = 7
y = -7 / 3
Put y = -7/3 in 1st equation, we get
x - 2 ( -7/3 ) = 3
x + 14 / 3 = 3
x = ( 3 × 3 ) / 14
x = 9 / 14
Thus we get our answer which is
x = 9 / 14 & y = -7 / 3
