A
system
of
equations
is
a
set
of
two
or
more
equations
together.
There
are
several
ways
that
we
can
solve
them!
A system of equations is a set of two or more equations together. There are several ways that we can solve them!
Method 1: Graphing
After graphing both equations on the same coordinate plane, you will then
be able to tell what type of solution it has based on what it looks like!

METHOD 3: SUBSTITUTION
To "substitute" means to "replace" so we can replace a variable
in one equation with a given value from another equation.

METHOD 4: ELIMINATION
To "eliminate" means to "get rid of" so we can add or subtract
the equations to "get rid of" one of the variables.

graph
the
inequalities
on
the

coordinate
plane.
A System of Inequalities is a set of two or more inequalities. To solve them, graph the inequalities on the same coordinate plane.
Remember that our solution is where the shaded regions overlap!
