tìm x:x-4368=3484*4
Tìm x
x - 4368 = 3484 x 4
x - 4368 = 3484 x 4
x - 4368 = 13 936
x = 13 936 + 4368
x = 18 304
\(x\) - 4368 = 3484 x 4
\(x\) - 4368 = 13936
\(x\) = 13936 + 4368
\(x\) = 18304
\(x-4368=3484\times4\)
\(=>x-4368=13936\)
\(=>x=13936+4368\)
\(=>x=18304\)
Câu 8: Tìm X:
X - 4368 = 3484 x 4
X - 4368 = 3484 x 4
x - 4368 = 13936
x = 13936 + 4368
x = 18304
X - 4368 = 3484 x 4
X - 4368 = 13936
X = 13936 + 4368
X = 18304
x-4368=3484*4
a) Tìm X: X - 4368 = 3484 x 4
b) Tính bằng cách thuận tiện nhất 49 x 385 – 39 x 385
a)\(x-4368=13936=>x=13936+4368=18304\)
b)\(385*(49-39)=>385*10=3850\) nhé
x - 4368 = 3484 x 4
x - 4368 = 13936
x = 13936 + 4368
x = 18304
b) 49 x 385 - 39 x 385
= 385 x ( 49 - 39 )
= 385 x 10
= 3850
x - 4368 = 3484 x 4
x - 4368 = 13936
x = 13936 + 4368
x = 18304
b) 49 x 385 - 39 x 385
= 385 x ( 49 - 39 )
= 385 x 10
= 3850
Tìm x:
x-4/12=-5/6
\(x-\dfrac{4}{12}=-\dfrac{5}{6}\)
⇔\(x-\dfrac{1}{3}=-\dfrac{5}{6}\)
⇔\(x=-\dfrac{1}{2}\)
\(\Leftrightarrow x=-\dfrac{1}{2}\)
=>(x-4).6=12.(-5)
=>6x-24=-60
=>6x=-36
=x=-6
Tìm x:
X x 2/5 = 4/15

3.tìm x:x*0,25-72,5=22,2
tìm x:x*3+x*4+x=172
4.tổng 2 số là 68,2; thương 2 số là 4,5.tìm 2 số đó
5.hiệu 2 số là 0,6,thương 2 số cũng la 0,6.tìm 2 số đó
Tìm x:
x - 1/4 = 7/2 . -3/5
\(x-\dfrac{1}{4}=\dfrac{-21}{10}\)
\(x=\dfrac{-21}{10}+\dfrac{1}{4}\)
\(x=\dfrac{-42}{20}+\dfrac{5}{20}=\dfrac{-37}{20}\)
Tìm x:
X x 3/4 = 4/5

5/9 : x = 8/3
...................
...................
...................
x = 4/5 : 3/4
x = 16/15
x = 5/9 : 8/3
x = 5/9 x 3/8
x = 5/24
\(x=\dfrac{4}{5}\times\dfrac{4}{3}\)
\(x=\dfrac{16}{15}\)
-----------------------
\(x=\dfrac{5}{9}\times\dfrac{3}{8}\)
\(x=\dfrac{5}{24}\)
\(x\times\dfrac{3}{4}=\dfrac{4}{5}\)
\(x=\dfrac{4}{5}:\dfrac{3}{4}\)
\(x=\dfrac{4}{5}\times\dfrac{4}{3}\)
\(x=\dfrac{16}{15}\)
\(\dfrac{5}{9}:x=\dfrac{8}{3}\)
\(x=\dfrac{5}{9}:\dfrac{8}{3}\)
\(x=\dfrac{5}{9}\times\dfrac{3}{8}\)
\(x=\dfrac{15}{72}\)
\(x=\dfrac{5}{24}\)
