Polynomials
A system of equations is a set of equations with more than one variable dealing with the same material. If there are 2 variables, then the system must have 2 equations before it can be solved. 3 variables need 3 equations, etc.
It is a set of equations, which is also called a system of equations. There may be no solution, a single (unique) solution or more than one - including infinitely many.
Equivalent equations are equations that have the same solution set.
It is called the "soulltion set"
They are called equivalent systems.
A system of linear equations that has one unknown is a set of equations that all depend on the same variable. An example is y = 1 + 3x and y = 4 + 7x.
You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables. Then you solve the equation(s), using algebra.You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

You set the two equations equal to each other and then solve for the variable.
It is using a set of two equations, adding them together, eliminating one variable and finding the value of the other variable.
Equivalent Equations
A system of equations is a set of two or more equations with the same variables, graphed in the same coordinate plane
The analysis is based on a set of linear equations for a straight line and the separation of variable and fixed costs.
