B) 
Step-by-step explanation:
On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression
.
On the right, we have six -1s. So, we can represent the right with the expression
.
A)
Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:

B)
Now, we can solve the equation for x. Add 1 to both sides:

The left will cancel. Add on the right:

Finally, divide both sides by 5:

The left side will cancel. So, the value of x is:

You are not correct, the right answer should be 5-2 square root symbol. I couldn't find out how to put one there.
