Riješi b/8=frac{sqrt{100-x^2}}{40/3-x}

$$\frac { b } { 8 } = \frac { \sqrt { 100 - x ^ { 2 } } } { \frac { 40 } { 3 } - x }$$

Izračunaj b (complex solution)

$$b=\frac{24\sqrt{100-x^{2}}}{40-3x}$$

$$x\neq \frac{40}{3}$$

Koraci rješavanja linearne jednadžbe

Jednadžba je u standardnom obliku.

$$\frac{1}{8}b=\frac{\sqrt{100-x^{2}}}{\frac{40}{3}-x}$$

Pomnožite obje strane s 8.

$$\frac{\frac{1}{8}b}{\frac{1}{8}}=\frac{3\sqrt{100-x^{2}}}{\frac{1}{8}\left(40-3x\right)}$$

Dijeljenjem s \frac{1}{8} poništava se množenje s \frac{1}{8}.

$$b=\frac{3\sqrt{100-x^{2}}}{\frac{1}{8}\left(40-3x\right)}$$

Podijelite \frac{3\sqrt{-x^{2}+100}}{40-3x} s \frac{1}{8} tako da pomnožite \frac{3\sqrt{-x^{2}+100}}{40-3x} s brojem recipročnim broju \frac{1}{8}.

$$b=\frac{24\sqrt{100-x^{2}}}{40-3x}$$

Izračunaj b

$$b=\frac{24\sqrt{100-x^{2}}}{40-3x}$$

$$|x|\leq 10$$

Izračunaj x
