Question 372373
(-3x/4)+y/3=5/12 
(-9x+4y)/12= 5/12
multiply by 12
-9x+4y=5......................1
x/5-y=4/5
(x-5y)/5 = 4/5
multiply by 5
x-5y = 4......................2
..
multiply equation 2 by 9
9x-45y=36
add to (1)
-45y+4y=36+5
-41y=41
/-41
y =-1
..
plug value of y in 1
-9x-4=5
-9x= 4+5
/-9
x=-1
