y=3
1) Since we want to find jut the y-coordinate, let's eliminate the x using the Method of Addition/Elimination
Since the Least Common Multiple of 3 and 5 is 15. Let's multiply both equations to get 15x and -15x and eliminate those x-terms.
5x-2y=4 x -3
3x-4y=-6 x 5
-15x +6y =-12
15x -20y=-30
------------------------
-14y = -42 Divide both sides by -14
y= 3
2) So y= 3, for this Linear System solution.
