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
In a two step equation, you need to do another step.
Yes, for solving simultaneous 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.
The difference is that first you have to understand the problem and translate it into an equation (or 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.
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.
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.
In a two step equation, you need to do another step.
Solving inequalities and equations are the same because both have variables in the equation.
Yes, for solving simultaneous equations.
Because linear equations are based on algebra equal to each other whereas literal equations are based on solving for one variable.
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.
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.
Solving the equation.
It is about finding a value of the variable (or variables) that make the equation a true statement.
