x=10000

tích mình nha i love you

10000:x=1

=>x=10000:1

x=10000

Ai tick mik mik se tick lai cho

1+1x1 = 2

OK nha

= ? bn nao nhanh mik se k

1 + 1 x 1

=1+1

=2

^_^

= 2 

mk k cho :D

=2

tk mk nhé

=2

hok tốt

tk đi

a, | x - 3/4 | = 1/2

=>\(\orbr{\begin{cases}x-\frac{3}{4}=\frac{1}{2}\\x-\frac{3}{4}=-\frac{1}{2}\end{cases}}\)

=>\(\orbr{\begin{cases}x=\frac{1}{2}+\frac{3}{4}\\x=-\frac{1}{2}+\frac{3}{4}\end{cases}}\)

=>\(\orbr{\begin{cases}x=\frac{2}{4}+\frac{3}{4}\\x=-\frac{2}{4}+\frac{3}{4}\end{cases}}\)

=>\(\orbr{\begin{cases}x=\frac{5}{4}\\x=\frac{1}{4}\end{cases}}\)

Vậy....

a) \(|x-\frac{3}{4}|=\frac{1}{2}\)

\(< =>\orbr{\begin{cases}x-\frac{3}{4}=\frac{1}{2}\\x-\frac{3}{4}=-\frac{1}{2}\end{cases}}\)

\(< =>\orbr{\begin{cases}x=\frac{1}{2}+\frac{3}{4}\\x=-\frac{1}{2}+\frac{3}{4}\end{cases}}\)

\(< =>\orbr{\begin{cases}x=\frac{5}{4}\\x=\frac{1}{4}\end{cases}}\)

Vay : x = 5/4 hoặc x =  1/4

b)\(saide\)

Sai de ban oi

x + 900 = 100 +1500

x + 900 = 1600

          x = 1600 - 900

         x = 700

ai nhanh mik k va k lai mik nha

mik nhanh nh

ất k mik ^_^

x + 900 = 100 + 1500

x + 900 = 1600

x = 1600 - 900

x  =      700

X+900=100+1500

X+900=1600

X=1600-900

X=700

Vậy X=700

7000-6000= 1000 

k nha ^-^

7000 - 6000 = 1000.

7000-6000=1000   ai k mik mik k lai

200 + 1000 = 1200

ai tk mk mk tk lại

200+1000=1200

= 1200 k mk mk k lại

5+5+5=5x3=15

k mình nha

=15 nha

5+5+5 = 15
