Step-by-step explanation:
4y+10x = -11xy ..... eq. 1
12x-21y = 17xy ....... eq. 2
eq.1 * 12 = 120x + 48y = -132xy ....eq.3
eq.2*10 = 120x-210y = 170xy .....eq.4
eq. 3 and eq.4 :
120x+48y = -132xy
120x-210y = 170xy
eq.3 - eq.4 :
-48y+210y = -302xy
162y = -302xy
x = 162/302 = 81/151
120x-210y = 170xy
120(81/151) = 170(81/151)y+210y
y = ???
