15x-8y=28. ... (I)

17x-12y=75. ... (II)

by multiplying equation (I) by 3 and equation (II) by 2 we get

45x-24y=84. ... (III)

34x-24y=150. ... (IV)

by subtracting equation (III) from equation (IV) we get

-11x=66

x=-6

putting x=-6 in equation (I) we get

15 (-6)-8y=28

-90-8y=28

-8y=118

y=-59/4
