Explanation Formula used: Substitution method is used to solve the linear system of equations as well as nonlinear system of equations for one or more variables. Quadratic equation formula: y 1 , 2 = − b ± b 2 − 4 a c 2 a Calculation: Consider the system of equations, x + y = 5 …… (1) x 2 + y 2 = 4 …… (2) Solve for y in equation (1), x + y = 5 y = 5 − x Therefore, y = 5 − x …… (3) Substitute equation (3) into (2), x 2 + y 2 = 4 x 2 + ( 5 − x ) 2 = 4 x 2 + x 2 <
