How Many System of Linear Equations?
In mathematics, a linear equation is defined as an expression where each term in the variable has an exponent of one. If it is represented in a graph then it results in a straight line. The straight-line equation y=mx+c is an example of a linear equation.
Generally, the form of a linear equation is Ax+B=C, where A, B, and C are constants and x is a variable. Moreover, the linear equations can be written in three distinct ways, they are
- Linear equation in one variable
- Linear equation in two variables
- Linear equation in three variables
How to Solve Solving System of Linear Equations using Cramers Rule(2 Variables)?
The step-by-step process of solving the Solving System of Linear Equations using the Cramers Rule(2 Variables) is given here. Follow the steps carefully and learn manually to solve the equation:
- First, rearrange the equation by placing the constant terms on one side and the terms of the variable on another side by using arithmetic operations on both sides of the equation.
- Solve the calculations and eliminate the constants.
- Separate the variable on one side by adding on both sides of the equation.
- Simply calculate and find the value of the variable.
