Answer:

Step-by-step explanation:

x - y = 2√3     given

-y = -x + 2√3  subtract x from both sides

y = x - 2√3     multiply both sides by -1

 

xy = 1                  given

x(x - 2√3) = 1      substitution

x2 - 2x√3 = 1       distribute

x2 - 2x√3 - 1 = 0  subtract 1 from both sides

 

Can you solve for x then y?
