8/3x-2 + 45/4y+3 = 5 ; 12/3x-2 - 30/4y+3 = 1

8/3x-2 + 45/4y+3 = 5 .........(i)

12/3x-2 - 30/4y+3 = 1................(ii)

Let 1/3x-2 = m and 1/4y+3 = n

8m + 45n = 5 .................(iii)

12m - 30n = 1.............(iv)

Continuing:

2×(iii): 16m+90n=10 ......(v)

3×(iv): 36m-90n=3 .........(vi)

(v)+(vi): 52m=13, m=¼; substitute for m in (iii): 2+45n=5, 45n=3, n=1/15.

So 3x-2=4, 3x=6, x=2;

4y+3=15, 4y=12, y=3.
