Alright, the first step is very simple
So basically subtract 6ab^2 from the first equation and you will get the second equation so 6ab^2 = 6
\(6ab^2 = 6\)
\(ab^2 = 1\)
now, you are asking for a - b
\(b^2 = 1/a\)
\(\cdot 1/b\) on both sides
\(b = 1/ab\)
im just doing every possible thing i can do bc this is my first time seeing this so im doing it as well as you sorry
\(ab = 1/b\) ok that might be useful
oh......
\(a^3 + 3 = 679\)
\(a^3 = 676\)
\(a \approx 8.77639\)
so b is 1/ whatever that is. Square rooted.....
its approximately 8.43883.... probably not correct, looking at the numbers. Maybe its like the square root of something?
its like \(\sqrt{71.212}\) not exacly but close
