0,25%x + $\frac{2}{12}$ = $\frac{-4}{5}$ 0,25%x = $\frac{-4}{5}$ – $\frac{2}{12}$ 0,25%x = $\frac{-29}{30}$ ⇔ $\frac{1}{400}$x = $\frac{-29}{30}$ x = $\frac{-29}{30}$ : $\frac{1}{400}$x =$\frac{-1160}{3}$ Bình luận
Đáp án:X=-1160/3
0,25%x + $\frac{2}{12}$ = $\frac{-4}{5}$
0,25%x = $\frac{-4}{5}$ – $\frac{2}{12}$
0,25%x = $\frac{-29}{30}$
⇔ $\frac{1}{400}$x = $\frac{-29}{30}$
x = $\frac{-29}{30}$ : $\frac{1}{400}$x =$\frac{-1160}{3}$
