In some simple cases, factoring allows you to find solutions to a quadratic equations easily.Factoring works best when the solutions are integers or simple rational numbers. Factoring is useless if the solutions are irrational or complex numbers. With rational numbers which are relatively complicated (large numerators and denominators) factoring may not offer much of an advantage.
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.
Equations = the method
It really depends on the type of equation. Sometimes you can know, from experience with similar equations. But in many cases, you have to actually do the work of trying to solve the equation.
Solving equations and inequalities both involve finding the values of variables that satisfy a given mathematical statement. In both cases, you apply similar algebraic techniques, such as adding, subtracting, multiplying, or dividing both sides of the equation or inequality. However, while equations have a specific solution, inequalities can have a range of solutions. Additionally, when multiplying or dividing by a negative number in inequalities, the direction of the inequality sign must be reversed, which is a key difference from solving equations.
It is about finding a value of the variable (or variables) that make the equation a true statement.
Yes, radical equations can sometimes have extraneous solutions. When solving these equations, squaring both sides to eliminate the radical can introduce solutions that do not satisfy the original equation. Therefore, it is essential to check all potential solutions in the original equation to verify their validity.
The answer depends on the nature of the equation. Just as there are different ways of solving a linear equation with a real solution and a quadratic equation with real solutions, and other kinds of equations, there are different methods for solving different kinds of imaginary equations.

The system of equations can have zero solutions, one solution, two solutions, any finite number of solutions, or an infinite number of solutions. If it is a system of LINEAR equations, then the only possibilities are zero solutions, one solution, and an infinite number of solutions. With linear equations, think of each equation describing a straight line. The solution to the system of equations will be where these lines intersect (a point). If they do not intersect at all (or maybe two of the lines intersect, and the third one doesn't) then there is no solution. If the equations describe the same line, then there will be infinite solutions (every point on the line satisfies both equations). If the system of equations came from a real world problem (like solving for currents or voltages in different parts of a circuit) then there should be a solution, if the equations were chosen properly.
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.
Bogomol'nyi-Prasad-Sommerfield bound is a series of inequalities for solutions. This set of inequalities is useful for solving for solution equations.
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.
Solving inequalities and equations are the same because both have variables in the equation.

Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable.
