tìm x 11/13 – (5/42 – x) = -(15/28 – 11/13) 31/07/2021 Bởi Allison tìm x 11/13 – (5/42 – x) = -(15/28 – 11/13)
Bạn tham khảo : $\dfrac{11}{13} – (\dfrac{5}{42} – x) = – (\dfrac{15}{28} – \dfrac{11}{13})$ $⇒ \dfrac{11}{13} – (\dfrac{5}{42} – x) = \dfrac{113}{364}$ $⇒ \dfrac{5}{42} – x = \dfrac{421}{364}$ $⇒ x = \dfrac{-1133}{1092}$ Bình luận
11/13-(5/42-x)=(-15/28-11/23) 11/13-(5/42-x)=-653/644 5/42-x=11/13-653/644 5/42-x=-1405/8372 x=5/42-1405/8372 x=-625/12453 Bình luận
Bạn tham khảo :
$\dfrac{11}{13} – (\dfrac{5}{42} – x) = – (\dfrac{15}{28} – \dfrac{11}{13})$
$⇒ \dfrac{11}{13} – (\dfrac{5}{42} – x) = \dfrac{113}{364}$
$⇒ \dfrac{5}{42} – x = \dfrac{421}{364}$
$⇒ x = \dfrac{-1133}{1092}$
11/13-(5/42-x)=(-15/28-11/23)
11/13-(5/42-x)=-653/644
5/42-x=11/13-653/644
5/42-x=-1405/8372
x=5/42-1405/8372
x=-625/12453
