Dear Aspirant,
Matrix method is a method to solve linear equations using matrix general formulas.
Suppose we have given two equations having 2 variables x and y, and we want to find them. T hen we can find them using matrix method.
Ex. x+2y = 2, 3y+4x= 3. Now we make 3 matrices A , B and X
A= [ 1 2 B = [ 2 X= [x
3 4 ] 3] y]
Now we use this equation to find value of x and y :
A*X = B or X= A^-1*B
Now we can find A^-1 easily and hence we can easliy find values of x and y.
Since in the question you have provided only 1 equation with 3 variables , so its impossible to solve 1 single equation alone. Please mention other equations too. Only then we can help you.
Hope you got it.
Question : If $x+y+z = 9$, then the value of $(x−4)^3+(y−2)^3+(z−3)^3−3(x−4)(y−2)(z−3)$ is:
Question : Simplify the given expression. $\frac{x^3+y^3+z^3-3 x y z}{(x-y)^2+(y-z)^2+(z-x)^2}$
