Equations using multiple variables, or powers of variables, may not provide a simple numerical value for a given variable. Equations that are solvable using the quadratic formula may result in two values.

Arthur Cayley

A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.

Two linear equations that are parallel with have the sameslope, or the m value in y = mx + b will be the same.For example, y = 3x + 5 is parallel to y = 3x - 6

if the linear equation is x+y=1 means we are having the graph points (1,0) (2,-1)....using this graph we can draw the graph

You cannot solve one linear equation in two variables. You need two equations that are independent.

You can solve the system of equations with three variables using the substitute method, or using matrix operations.

The answer depends on whether they are linear, non-linear, differential or other types of equations.

Equations = the method

In algebraic equations, exponents can contain variables. They can be solved for by using logarithmic rules for exponents.

In math, the purpose of Cramer's rule is to be able to find the solution of a system of linear equations by using determinants and matrices. Cramer's rule makes it easy to find a system of equations that have many unknown variables.

In that instance, it means that the lines never touch.
