Linear Algebra Examples

$x^{2} + 2 x y - y^{2} = - 17$ , $x^{2} - y^{2} = - 45$

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.
