Polynomial Equations of Degree One
Equations in which the exponent of the variable is always one and the variable never appears as a divisor or under a radical sign are called polynomial equations of degree one.
Shortcuts for Solving Equations
A review of shortcuts that can be used in solving equations.
Solving Systems with Substitution Example
The substitution method can be used when one of the equations in a system has been solved for one of its variables. An example demonstrates.
