4×x53×x4=3×x101=x=4

That is the answer straight from the site calculator. I putit in using Math(Input=result) tab.

Now I'll do it by hand - When you do it you should line up all the equal signs.

I multiplied by 20 because 20 is  the LCD Lowest common denominator and that got rid of all the fractions.

4x53x4=3x10120×(4x53x4)=20×(3x101)16x15x=6x20x=6x205x=20x=4

I truly hate the result from the site calculator.

The result, x=4, is correct, but the presentation, saying that both sides of the original equation  are equal to x and equal to 4 is most certainly not correct.

Yes, thank you for your input Bertie,

I don't like that either, maybe Andre could put an arrow in the middle - that would be an improvement.

Andre is very busy with a great many problems and I don't want to pester him all of the time but I do hope some of these 'annoying issues' will eventually be improved.

I probably should set up a list of these more minor issues somewhere so that eventually we can talk to Andre about them.

I'm in complete agreement with Bertie's comment here too!
