Question

conclusion of simultaneous linear equations

plz answer me quick and follow me ​

Answer 1

three are four ways in which we can

solve systems of linear equations. Sometimes substitution is the best method and sometimes we should use elimination or graphing. When you reflect back on this webquest in your notebook you should be thinking about which method you thought was the easiest to use and why. Also, while you have your notebooks out I want you to try and come up with another real world situation in which we might find a system of equations. By applying Cross multiplication method, we can also solve this, on this basis,

A1 x + B1y + C1 = 0, and

A2x + B2y + C2 = 0.

The coefficients of x are: A1 and  A2.

The coefficients of y are: B1 and B2.

The constant terms are: C1 and  C2.

x/(b1c2 -b2c1)=y/(c1a2-c2a1)=1/(a1b2-a2b1)

And there are three types of solutions

1. unique

2. infinite

3. no solution

Answer 2

Hey mate✌

You answer is....

Simultaneous Linear Equations

Consider two linear equations in two variables, x and y, such as

2x - 3y = 4

3x + y = 1

Instead of one equation in one unknown, we have here two equations and two unknowns. In order to find a solution for this pair of equations, the unknown numbers x and y have to satisfy both equations. Hence, we call this system or pair of equations or simultaneous equations. We now focus on various methods of solving simultaneous equations.

Intersection Point of a Line with a Horizontal or Vertical Line

We first consider the special cases of solving a pair of simultaneous linear equations when one of the two lines is either horizontal (ay = b) or vertical (cx = d); the solution in these cases is easily found by substitution.

Hope it helps you✌
