What is a method used for solving systems of equation in which one of the equations is substituted into another?

It is called substitution. Solve one of the equations for a single variable and substitute it into the other.
x+y=10 y=10-x
2x-y=-4
2x-(10-x)=-4
2x-10+x=-4
3x-10=-4
3x=6
x=2
x+y=10
(2)+y=10
y=8

How is solving a two step equation different from one step equations?
In a two step equation, you need to do another step.
Is The elimination method is useful when you can eliminate one of the variable terms from an equation by adding or subtracting another equation?
Yes, for solving simultaneous equations.
What would you need to help you with it comes to solving equations?
When solving equations remember that whatever operations are performed on the LHS of the equation must be performed on its RHS to keep the equation in balance.
How would solving a literal equation differ from a one or two step equation?
The difference is that first you have to understand the problem and translate it into an equation (or equations).
How we find the root of a equations?
That is the same as solving the equation. There is no single and simple method to solve ANY equation. You have to learn lots of different methods, to solve different types of equations. You might start by picking up an algebra book - to a large part, such books deal with the topic of solving equations.
What is usually the first step in solving a system of equation by substitution?
The first step is to solve one of the equations for one of the variables. This is then substituted into the other equation or equations.
What are you trying to find when solving a system of linear equations?
You are trying to find a set of values such that, if those values are substituted for the variables, every equation in the system is true.
How is solving a two step equation different from one step equations?
In a two step equation, you need to do another step.
How are the rules for solving inequalities similar to those for solving equations?
Solving inequalities and equations are the same because both have variables in the equation.
How does solving a literal equation differ from solving a linear equation?
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
Is The elimination method is useful when you can eliminate one of the variable terms from an equation by adding or subtracting another equation?
Yes, for solving simultaneous equations.
What would you need to help you with it comes to solving equations?
When solving equations remember that whatever operations are performed on the LHS of the equation must be performed on its RHS to keep the equation in balance.
How do you solve imaginary equations?
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.
What do you call finding the value of the variables that make equations true?
Solving the equation.
What is solving equations about?
It is about finding a value of the variable (or variables) that make the equation a true statement.
