Linear Algebra Examples

$x + y + 2 = 0$ , $x^{2} + y^{2} + 4 y - x = - 4$

Step 1

Gaussian Elimination cannot be used.

Step 2

Decompose a solution vector by re-arranging each equation represented in the row-reduced form of the augmented matrix by solving for the dependent variable in each row yields the vector equality.
