How Calculators can be used
with the System of Equations

Now, there are times when time or complicity of
calculations makes it even harder. This is where
online calculators or math solvers come in. With
the advance of technology, such math solvers
have become increasingly popular and useful.

They’re
especially
handy when you
are short of time
and need fast
answers, or
when such
calculations are
just a part of
another lengthy
process.

One such solver is the system of equations calculator.
There are several sites where you can find such fast
working solvers like say MathPapa or WebMath. These
solvers are pretty much self-explanatory, and these
sites usually have demos and examples which you
could go through before starting your own calculations.

In the system of
equations
calculator, you
need to input the
equations
separated by
commas. For
example, let us
take two simple
equations -
x + y = 10 and x +
2y = 16.

You will need to
input these two
equations in the
box given to you,
separated with
commas like
x + y = 10, x + 2y
= 16. Once you
press the button to
calculate it, it will
give you the
answer of x = 4
and y = 6.

These are quite simple equations that we have
taken as examples. These solvers can handle
more complicated ones too. The best part is that
such calculators also give you a step by step
explanation. Thus you can check the answers
and understand the process better.

• The system for
equations
calculator can
be used to solve
expressions and
also for double
checking
answers for
equations
having x.
Checking answers

For example,
let’s say we
solved an
equation 3x + 2
= 8 and we got
an answer of x
= 2. You can
input 2 in the
original
equation 3x + 2
= 8 @ 2 and
check the work.

If the answer is
correct, then the
calculator like
MathPapa would
show an equal
green sign. If you
input a wrong
answer, it would
give you just the
opposite and
show you an
equal red sign.

The same can also
be used to
determine
equations are
having x as well as
y. All you need to
do is enter both the
equations which
would be
separated by
semicolon and
should be followed
by @.

For example,
x + y = 10; x +
2y = 16 @ (4,
6).
Every
software
would have
slightly
different
features and
is mostly
compatible
with all
devices.

In some calculators like MathPortal, you have a choice
wherein you can choose the way of solving your
equations. That is you can opt to use the default
method of addition or elimination or the method
followed by Cramer’s rule and also determine whether
you want to see the steps or just get the answer.
