Using left-to-right elimination method, we can eliminate the y variable in the first equation by adding 2 times the second equation to it. This results in:
3x + 2y = 3 
5x + 3y = 10 
Next, we can eliminate the y variable in the second equation by adding -3/2 times the first equation to it. This results in: 
3x + 2y = 3 
7/2 x = 19/2 
Solving for x, we get x=19/7. 
Substituting this value back into the first equation, we get y = -6/7. 
Therefore, the solution is (19/7, -6/7), which is option A.
