A System of Linear Equations: a set of two or
more linear equations that are to be solved at the same time.
A Solution to a System: an order pair that is
a solution to every equation in the system.
Solving a Linear System Graphically: graph
the equations on the same coordinate plane. The coordinates of
the point of intersection are the ordered pair solution.
Consistent System: a system with at least one
solution.
Inconsistent System: a system with no
solutions (the lines are parallel).
Independent Equations: equations whose graphs
do not coincide.

Step 1
: Enter your homework problem in an easy WYSIWYG (What you see is what you get) algebra editor:
Step 2 :
Let Algebrator solve it:
Step 3 : Ask for an explanation for the steps you don't understand:
Algebrator can solve problems in all the following areas:
simplification of algebraic expressions (operations
with polynomials (simplifying, degree, synthetic division...), exponential expressions, fractions and roots
(radicals), absolute values)
factoring and expanding expressions
finding LCM and GCF
operations with complex numbers
(simplifying, rationalizing complex denominators...)
solving linear, quadratic and many other equations
and inequalities
(including basic logarithmic and exponential equations)
solving a system of two and three linear equations
(including Cramer's rule)
