선형 방정식의 해를 찾는 단계

수식의 양쪽 모두에 12을(를) 곱합니다.

$$672000=12A\times \frac{1-\left(1+\frac{\frac{8.15}{100}}{12}\right)^{-48}}{\frac{8\times \frac{15}{100}}{12}}\left(1+\frac{\frac{815}{100}}{12}\right)$$

분자와 분모 모두에 100을(를) 곱하여 \frac{8.15}{100}을(를) 확장합니다.

$$672000=12A\times \frac{1-\left(1+\frac{\frac{815}{10000}}{12}\right)^{-48}}{\frac{8\times \frac{15}{100}}{12}}\left(1+\frac{\frac{815}{100}}{12}\right)$$

5을(를) 추출 및 상쇄하여 분수 \frac{815}{10000}을(를) 기약 분수로 약분합니다.
