Hi !

In this video, we are going to learn about Cramer's rule.

In linear algebra, Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution.

To solve a system of three equations in three variables using Cramer's Rule, replace a variable column with the constant column for each desired solution: x=DxD, y=DyD, z=DzD.

At 5.39 i think there is an inadvertent error. X= ∆x/∆. You have mentioned x=∆x/x. I think it just happened in flow.

If this of question is in exam so what we will we have to do

2x + 8y + 5z = 5
X + 2y - z = 2
Y. + X + z = -2

What will be it's answer
Make a video on this question sir
