URGENT! What is the solution set of the following system of equations?

x + y = 0

x - y + 2 = 0

x + y = 0 is x = − y.

x - y + 2 = 0 is x = y − 2.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
