What are the three different approaches to solving simultaneous equations?
There are three different approaches to solve the simultaneous equations such as substitution, elimination, and augmented matrix method. Among these three methods, the two simplest methods will effectively solve the simultaneous equations to get accurate solutions. Here we are going to discuss these two important methods, namely,
What are some examples of simultaneous equations?
Simultaneous equations are two or more algebraic equations that share common variables and are solved at the same time (that is, simultaneously). For example, equations x + y = 5 and x - y = 6 are simultaneous equations as they have the same unknown variables x and y and are solved simultaneously to determine the value of the variables.
How do you solve simultaneous equations?
The simultaneous equations can be solved by using the elimination method. After the value of one variable is found, it is substituted in the equation to find the other variable values.
What is the general form of simultaneous linear equations?
The general form of simultaneous linear equations in two variables is as shown: ax +by = c where ‘a’ and ‘p’ is the coefficient of x and, ‘c’ is the constant. px + qy = r where ‘b’ and ‘q’ are the coefficient of y and, ‘r’ is the constant.
