Good day everyone,

I have problem-solving this system of equations using Iterative Projection Theorem. Anyone with a better explanations please.

The equation is as stated below. 

Solve this set of equations using the iterative projection theorem.

(x₁ - 2)² + (2x₂² - 6)² - 5 = 0

(x₁² - 4)² + (x₂ - 10)² - 39 = 0

Take the provisional values of  x₁ and x₂ as x⁰₁ = 5, x⁰₂ = 4, 

Thank you in anticipation
