It is called solving by elimination.
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.

Linear Equations are equations with variable with power 1 for eg: 5x + 7 = 0 Simultaneous Equations are two equations with more than one variable so that solving them simultaneously
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.
When solving a system of linear equations using the elimination method, multiplying the bottom equation by 3 can help align the coefficients of one of the variables, making it easier to eliminate that variable. This step works because it maintains the equality of the equation while allowing for the addition or subtraction of the equations to eliminate the variable effectively. By strategically choosing a multiplier, you can simplify the process of finding the solution to the system.
To solve equations effectively in four steps, consider these types: Linear Equations: Isolate the variable by adding or subtracting terms, then divide or multiply to solve. Quadratic Equations: Rearrange to standard form, factor or use the quadratic formula, simplify, and solve for the variable. Rational Equations: Clear the denominators, simplify the resulting equation, isolate the variable, and solve. Exponential Equations: Take the logarithm of both sides, isolate the variable, and simplify to find the solution. Systems of Equations: Use substitution or elimination to reduce the system, isolate one variable, and solve for it.
The last step in solving a system of non-linear equations by substitution is typically to substitute the value obtained for one variable back into one of the original equations to find the corresponding value of the other variable. After finding both values, it's important to check the solutions by substituting them back into the original equations to ensure they satisfy both equations. This verification confirms the accuracy of the solutions.
Yes, a system of linear equations can be solved by substitution. This method involves solving one of the equations for one variable and then substituting that expression into the other equation. This process reduces the system to a single equation with one variable, which can then be solved. Once the value of one variable is found, it can be substituted back to find the other variable.
The addition method is sometimes referred to as the "elimination method." This technique is used in solving systems of linear equations by adding or subtracting the equations to eliminate one variable, making it easier to solve for the other variable.
Solving linear equations is hard sometimes.

NO
A linear system is a set of equations where each equation is linear, meaning it involves variables raised to the power of 1. Solving a linear system involves finding values for the variables that satisfy all the equations simultaneously. This process is used to find solutions to equations with multiple variables by determining where the equations intersect or overlap.
