The notation in its current form isn't entirely clear.
Did you mean to write 
? The 4 isn't in the square root.
If so, then the expression is in simplest form because we cannot simplify 
any further (note how 10 doesn't have any perfect square factors other than 1).
Also, the 3/4 portion is fully reduced already.
------------------------
Or,
Did you mean to write 
? This time the 4 is inside the square root.
If so, then we can simplify like this
This means that 
Since they are both equal to y, you can set -7x and x+8 equal to each other.
- 7x = x + 8 and solve for x then use what you got for x to solve for y
