Solving System of Equation by Elimination Method: To solve a system of linear equations in two variables, we can apply the technique of variable elimination method. By using one equation, we have to express one variable as a function of the other and then substitute that in the other ...
To solve a system by elimination, add or subtract the equations of the system in order to "eliminate" one of the variables. Continue this process until only one variable is known. Then, substitute this known variable into the preceding equations to find the remaining variables. What is the ...
