Select the best method of finding an accurate solution to a system of linear equations
Flura [38]

The best method for solving the system of linear equation is by the use of algebraic methods.

The system of linear equations can be solved by using the method of simultaneous equations. Here we are given two equations and two unknown variables. We can solve the same by eliminating one of the variables and then either adding or subtracting, find the value of the other variable. Once we know the value of one variable, then we can substitute its value in any one given equation and find the second variable. This method is said to be accurate and does not involve any error.

Hence answer is : USE ALGEBRAIC METHODS
