a,$\frac{3}{4}$ – x = 1 x = $\frac{3}{4}$ – 1 x = $\frac{-1}{4}$ vậy x = $\frac{-1}{4}$ b, x + 4 = $\frac{1}{5}$ x = $\frac{1}{5}$ – 4 x = $\frac{-11}{5}$ vậy x = $\frac{-11}{5}$ c, x – $\frac{1}{2}$ = 2 x = $\frac{1}{2}$ + 2 x = $\frac{5}{2}$ vậy x = $\frac{5}{2}$ d, x+ $\frac{5}{3}$=$\frac{1}{81}$ x = $\frac{1}{81}$ – $\frac{5}{3}$ x = $\frac{-134}{81}$ vậy x = $\frac{-134}{81}$ hok tốt Bình luận
Đáp án: Giải thích các bước giải: 3/4-x=1 =>x=3/4-1=-1/4 x+4=1/5 x=1/5-4=-19/20 x-1/2=2 =>x=2+1/2=5/2 x+5/3=1/81 =>x=1/81-5/3=-134/81 No copy Bình luận
a,$\frac{3}{4}$ – x = 1
x = $\frac{3}{4}$ – 1
x = $\frac{-1}{4}$
vậy x = $\frac{-1}{4}$
b, x + 4 = $\frac{1}{5}$
x = $\frac{1}{5}$ – 4
x = $\frac{-11}{5}$
vậy x = $\frac{-11}{5}$
c, x – $\frac{1}{2}$ = 2
x = $\frac{1}{2}$ + 2
x = $\frac{5}{2}$
vậy x = $\frac{5}{2}$
d, x+ $\frac{5}{3}$=$\frac{1}{81}$
x = $\frac{1}{81}$ – $\frac{5}{3}$
x = $\frac{-134}{81}$
vậy x = $\frac{-134}{81}$

Đáp án:
Giải thích các bước giải:
3/4-x=1
=>x=3/4-1=-1/4
x+4=1/5
x=1/5-4=-19/20
x-1/2=2
=>x=2+1/2=5/2
x+5/3=1/81
=>x=1/81-5/3=-134/81
