$\frac{-5}{7}$-|$\frac{1}{2}$-x|=$\frac{-11}{4}$ 02/09/2021 Bởi Charlie $\frac{-5}{7}$-|$\frac{1}{2}$-x|=$\frac{-11}{4}$
1/2 – x = -5/7 -( -11/4) TH1 : 1/2 – x = 57/28 x = 1/2 – 57/28 x= -43/28 TH2 : 1/2 – x = – 57/28 x = 1/2 – ( -57/28) x= 71/28 Vậy x = -43/28 hoặc 71/28 Bình luận

1/2 – x = -5/7 -( -11/4)
TH1 : 1/2 – x = 57/28
x = 1/2 – 57/28
x= -43/28
TH2 : 1/2 – x = – 57/28
x = 1/2 – ( -57/28)
x= 71/28
Vậy x = -43/28 hoặc 71/28
