History about Linear Equations with two variables. Around years ago, Babylon knew how to solve a simple linear equation with two variables. Evidence from about BC indicates that the Egyptians also marhs how to solve problems involving a system of two equations in two unknown quantities, including quadratic equations.
He recognized the need for conditions to be placed teafhing unknown variables in order to find a solution. With the turn into the 19th century Gauss introduced a procedure to be used for solving a system of linear equations.
Cayley, Euler, Sylvester, and others changed linear systems into the use of matrices to represent. Gauss brought his theory to solve systems of equations proving to be the most effective basis for solving unknowns. Five years hence, the age of Ch 13 Maths Class 10 Ncert Solutions Teachoo Unit Jacob will be three times that of his son. What are their present ages?
