Using a Givens transformation for elimination. In the Givens transformation a rotation matrix is used to eliminate elements. The idea of the transformation is basically to take two elements apqand aqqand regard them as a 2 dimensional vector. This vector is rotated by the angle φ and the ang...
To solve for x in a bracket we use distributive law and remove the bracket, move all the x terms to one side and constant to the other side and find the unknown x. For example, 2(x−3) = 4 By using distributive law, 2x - 6 = 4 ⇒ 2x = 4 + 6 ⇒ 2x = 10 ⇒ x ...

Plug that value into either original equation, and solve for the remaining unknown. In the elimination method, we add or subtract equations within the system in order to eliminate a variable, enabling us to solve for a single unknown. Once we have its value, we can plug that into any ...
