Solve this equation
Explications :
(X*8)-5=(x*10) +2
[tex]8x -5 = 10x +2\\-5 -2 = 10x -8x \\-7 = 2x\\x =\frac{-7}{2}[/tex]
In mathematics, and particularly in linear algebra, a system of linear equations is a system of equations consisting of linear equations that relate to the same unknowns. For example:
[tex]x +2y +3z = 4\\2x +4z +6z = 9\\5x +3y +9z = 17[/tex]
Ou x, y et z sont des inconnues à trouver.
The solution of linear systems of equations belongs to the oldest problems in mathematics and these appear in many fields, such as in digital signal processing, linear optimization, or in the approximation of non-linear problems in numerical analysis. An efficient way to solve a system of linear equations is given by Gauss-Jordan elimination or Cholesky decomposition or LU decomposition. In simple cases, the Cramer's rule can also be applied.
