Answer:
First we will solve for x
Use radical rules
√11-√7÷11 -√7=x-y√77
write division as fraction
√11 -√7/11 -√7=x-y√77
√11 - √7/√11 -√7=x-y√77
√11 - √7/11-√7= x-y√77
-x=-y√77 -√11+√77/11+√7
Change the signs
x=y√77+√11-√77/11-√7
x=y√77+√11-√77/11-√7
Now we will solve for y
√11-√7÷11 -√7 = x-√77y
√11 -√7/11 -√7 =x-√77y
√11-√7/√11-√7=x-√77y
√11-√7/11-√7 = x-√77y
√77y= x-√11 +√77/11 +√7
y=×/√77- 1/√7 +1/11 +1/√11
y=x√77/√77-√7/7+ 1/11+ √11/11
y=x√77/77-√7/7+ 1+√11/11
