3/2016+3/2017-3/2018 / 5/2018-5/2017-5/2016

=3.(1/2016+1/2017-1/2018)/5.(1/2018-1/2017-1/2016)

=-3/5

Chúc bạn học tốt!

Bài 1:

a: x=4

nên x+1=5

\(A=x^5-x^4\left(x+1\right)+x^3\left(x+1\right)-x^2\left(x+1\right)+x\left(x+1\right)-1\)

\(=x^5-x^5-x^4+x^4+x^3-x^3-x^2+x^2+x-1\)

=x-1

=4-1

=3

First, I am going to visit Ha Long Bay for two days

Then, I am going to see Ngoc Son Temple in Ha Noi for a week

Next, I am going to visit Hue for a week.

After that, I am going to see the citadel

Next, I am going to stay at a friend's house in Nha Trang for three days

Then, I am going to stay with their uncle in Ho Chi Minh City for a week

After that, I am going to visit the beach and swim in Nha Trang

Next, I am going to visit my friend

Then, I am going to see a movie

After that, I am going to wath a soccer match

2x−92402x−9240=39803980⇒⇒2x−92x−9=240.3980240.3980=117117

2x−9=1172x−9=117⇒⇒2x=117+9=1262x=117+9=126⇒⇒x=126:2=63

Ta có 2x–9/240=39/80=117/240. suy ra 2x – 9 = 117

Từ đó tìm được x = 63 

\(2.x-\frac{9}{240}=\frac{39}{80}\)

\(\frac{39}{80}=\frac{117}{240}\)

\(\Rightarrow2.x-\frac{9}{240}=\frac{117}{240}\)

\(\Rightarrow2.x-9=117\)

\(\Rightarrow2x=126\)

\(\Rightarrow126:2=63\)

Vậy: x = 63

-3x - 10 = -2x -5 

<=>-3x+2x=10-5

<=>-x=5

<=>x=-5 

vậy ...

Ta có: -3x-10=-2x-5

\(\Leftrightarrow-3x-10+2x+5=0\)

\(\Leftrightarrow-x-5=0\)

\(\Leftrightarrow-x=5\)

hay x=-5

Vậy: x=-5

-5 nha
