Can a linear equation and a linear Equality be solved the same way?
Yes.
What are two symbolic techniques used to solve a system of linear equations in two variables?
I have never seen the term 'symbolic' used in this way. There are 4 methods used to solve a system of linear equations in two variables. Graphing, Substitution, Elimination, and Cramer's Rule.
Is 1 divided by w plus 18 equals 2 a linear equation?
Yes. By the way, w = -1/16
Whats the difference between a linear equation and a system of linear equations?
Quite simply, the latter is a group of the former.A system of linear equations is several linear equations taken together, each using the same group of unknowns. Usually, such a system provides one linear equation for each unknown (x, y, z, et al) that must be found (more complex systems can exist, though). You can use and manipulate these linear equations as you would a single linear equation to help solve for the unknowns. One way is to reduce all but one of the unknowns so that each can be expressed in terms of the remaining unknown and then solve for the remaining unknown which would in turn give you the others.
What is a linear equation or slope used everyday and in business?
A linear equation may be used to convert a unit price to a price for the quantity that you want. For example, if one bottle of drink costs C units then (at that same price) 5 bottles will cost 5*C units. It is used in the same way by businesses.
