I hope it work
Step-by-step explanation:
4x-5y=9 -6x+5y=-11adding both the equations
4x-5y=9
-6x+5y=-11
-2x+0y=-2
-2x=-2
Now divide both sides by -2
-2/-2 x= -2/-2
x=1Now putt the value of x in one of above equation to get value of y4(1)-5y=9now solve this-5y=9-4-5y=5divide -5 to both sidesy= -1These are he required value of x and yplease Brain-list the answer if u like it thanks...Ответ:
