Making my System of equations correctly interpreted in Wolfram Alpha

Posted 4 months ago

Hello, I'm here fitrst time.

I would like solve sytem of equations but the wolfram don't undrestand my command.

Below is my system od equations:

(a^3)b-((a-2c)^3)(b-2d)=12*145560

ab^3-(a-2c)(b-2d)^3=12*125560

(2((a-c)(b-d))^2)/((a-c)/d+(b-d)/c)=34567

ab-(a-2c)(b-2d)=1256

I enter it into Wolfram like this:

(a^3)*b-((a-2*c)^3)*(b-2*d)=12*145560 && a*b^3-(a-2*c)*(b-2*d)^3=12*125560 && (2*((a-c)*(b-d))^2)/((a-c)/d+(b-d)/c)=34545 && a*b-(a-2*c)*(b-2*d)=1234

I have got reply from Woflram like this: enter image description here

Please for help. What did I do wrong?

Best Regards
Arek
