Using left-to-right elimination method, we can eliminate y in the second equation:
-2x + 3y = 5
4x + 5y = 17

Multiply the first equation by 5 and the second equation by 3:
-10x + 15y = 25
12x + 15y = 51

Subtract the first equation from the second equation:
22x = 26
x = 1.18

Now substitute x into one of the original equations to solve for y:
-2(1.18) + 3y = 5
y = 2.12

Therefore, the solution is (1.18, 2.12), which matches option B.
