The fraction would be 35/100, in simplest form that is 7/20.
Given the system of the equation below;

We can use the elimination method to solve the systems of equations
Step 1: Subtract equation 2 from equation 1 and solve for x

Step 2: Sustitute x = 1 in equation 1

Therefore, the solution to the system of equation is
I^2 = (sqrt-1)^2 then the square cancels out so the answer is just
-1
