Formal computation : x/(ka) + b = 1/a
Formal computation : ax + a/(kb) = 1/b
Formal computation : kax ± pbx= k²a² - p²b²
Formal computation : k²a²+(ka±pb)/x=p²b²
Formal computation : x/(p²b²)-x/(k²a²)=(ka±pb)/(a*b)
Formal computation : b(x - 1/(ka)) = a or b(x - 1/a) = a/k
Formal computation : (ab)/(x/(ka)+b)=a+b or (ab)/(x/(kb)+a)=a+b
Formal computation : 1/(x/(ka)+1/b)=a or 1/(kx/a+1/b)=a
Formal computation x/(ka) + x/b = 1 or x/a + x/(kb) = 1
Formal computation : kb/(x+k²b)=1/(a+k) or b/(kx+pb)=1/(a+p)
Formal computation : 1/x = 1/(kb) - 1/a or 1/x = 1/b - 1/(ka)
Formal computation : x/(ab) + (ka)/b = 1/b or x/(ab) + a/b = k/b
