Odpowiedź :
Przykład a)
[tex]a-b=d\\a=d+b[/tex]
Przykład b)
[tex]ac+b=d\\ac=d-b|:a\\c=\frac{d-b}{a}[/tex]
Przykład c)
[tex]R=\frac{w}{a-b} |*(a-b)R(a-b)=w\\Ra-Rb=w\\Ra=w+Rb|:R\\a=\frac{w+Rb}{R} \\a=\frac{w}{R} +b[/tex]
Przykład d)
[tex]h=\frac{gt^2}{2} |*2\\2h=gt^2|:t^2\\g=\frac{2h}{t^2}[/tex]
Przykład e)
[tex]a=d(e+f)\\a=de+df\\df=a-de|:d\\f=\frac{a}{d} -e[/tex]
a)
[tex]a-b = d\\\\\boxed{a = b+d}[/tex]
b)
[tex]ac + b = d\\\\ac = d-b \ \ \ |:a\\\\\boxed{c = \frac{d-b}{a}}[/tex]
c)
[tex]R = \frac{w}{a-b} \ \ \ |\cdot(a-b)\\\\R(a-b) = w\\\\aR - bR = w\\\\aR = w + bR \ \ \ |:R\\\\\boxed{a = \frac{w}{R}+b}[/tex]
d)
[tex]h = \frac{gt^{2}}{2} \ \ \ |\cdot 2\\\\gt^{2} = 2h \ \ \ |:t^{2}\\\\\boxed{g = \frac{2h}{t^{2}}}[/tex]
e)
[tex]a = d(e+f)\\\\de+df = a\\\\df = a-de \ \ \ |:d\\\\\boxed{f = \frac{a}{d} -e}[/tex]
