explain elimination method
Answers
Answer:
The Elimination Method
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
Answer:
The elimination method is used to solve linear equations in two variables, where one of the variables is removed or eliminated.
Elimination method refers to multiplying the coefficients with a constant. In general, there are two broad classifications through which a pair of linear equations in two variables is solved. One classification is Graphical solution, in which the pair of simultaneous equations is solved by plotting the graphs of the given equations.
The meaning of solving simultaneous linear equations is to reduce the pair of equations to a single linear equation in one variable and then solve it using normal methods.
In the elimination method, the coefficients of the given equations are multiplied by a constant to make the coefficients of one variable same in both equations. Finally, anyone variable remains at the end, which can then easily be solved.
