AX+BX+CX = N |
|
|
| |
The calculator on this webpage solves equations
of the type shown above, for X,
when the values for A,B,
C, and N, are entered into the white boxes below. |
|
| |
Delete the numbers in the white boxes below, and
enter your own numbers. Then, left click with the mouse, on
the yellow or blue background, and the value of X will be calculated, in
the green box. |
|
| |
Scroll all the way down, beneath the calculator,
for additional instructions and contact information |

The formula in this green box cannot be seen, so
it is reproduced here: =E14/(E11+E12+E13) I created this formula by solving the equation
on the top of this page (AX+BX+CX= N) for X, and then I represented A, B,
C and N with the input cells.
|
|
| |
|
|
| |
The equation on top of this page (AX+BX+CX=N)
represents the set of equations that this calculator can solve.
All of the following are examples:
|
|
| |
|
2X+3X+5X=100 |
|
|
| |
|
|
|
|
|
| |
|
-6X-4X-90X=500 |
|
|
| |
|
|
|
|
|
| |
|
24X+26X+50X=-1000 |
|
|
| |
|
|
|
|
|
| |
|
(A=0), 20X+30X=200 |
|
|
| |
|
|
|
|
|
| |
|
(A=0 and B=0), 250X=1500 |
|
|
| |
|
|
|
|
|
| |
With this calculator you can enter positive as
well as negative numbers. You can also enter very large and
very small numbers, involving over 250 digits. |
|
| |
Numbers that have many digits will be displayed
in scientific notation, using the letter E. For example
900000000000000 is displayed as 9E+14, and 0.00000000000009 is displayed
as 9E-14. |
|
| |
(Note, the spreadsheet version of this
calculator uses an uppercase E. and the JavaScript version uses a
lowercase e.) |
