Why are linear equations also called first-degree equation?
Equations can be classified according to the highest power of the variable. Since the highest power of the variable in a linear equation is one, it is also called a first-order equation.
What is first degree equation?
A first-degree equation, also known as a linear equation, is an algebraic equation in which the highest power of the variable is one. It can typically be expressed in the form ( ax + b = 0 ), where ( a ) and ( b ) are constants, and ( x ) is the variable. The graph of a first-degree equation is a straight line, and it represents a constant rate of change between the variable and the constant terms. Examples include equations like ( 2x + 3 = 7 ) or ( y = 4x - 5 ).
Quadratic equation definition?
An equation of the second degree, meaning it contains at least one term that is squared.
When using the substitution to solve nonlinear system of equations you should first see if you can one variable if you can one variable in one of the equation in the system?
The general idea is to solve one of the equations for one variable - in terms of the other variable or variables. Then you can substitute the entire expression into another equation or other equations; as a result, if it works you should end up having one less equation, with one less variable.
Can you solve a variable with an equation?
When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.

What is is an equation with more than one variable called?
Simultaneous equation* * * * *No, simultaneous equations are two or more equations that have all to be true at the same time (simultaneously) for the solution.An equation with more than one variable is a multivariate equaion.Area = 0.5*Length*Height or a = 0.5*l*h for the area of a triangle has more than one variables, but it is certainly not simultaneous.An equation with a variable is called a single variable equation. An equation that has more than one variable is called as a multi-variable equation. A polynomial equation has one variable in different powers: a common example is quadratic equations.
Quadratic equation definition?
An equation of the second degree, meaning it contains at least one term that is squared.
An equation with a degree of 2?
An equation with a degree of 2 is called a quadratic equation. At least one term in the equation will have a variable raised to the second power, e.g. x²
Why quadratic equation is used?
It's quite convenient, for it offers a general method to solve any equation that involves a polynomial of degree two (in one variable).
What is an equation that is not true for any value of a variable?
linear equation in one variable

What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
What is it called when you have to get the variable alone on one side of an equation?
It is to make the variable the subject of the equation.
Why do you isolate the variable on one side the the equation when solving a linear equation?
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
