2087-x /27=2015 và bài này nữa 45*(463+x)=44955
2087-x chia 27= 2015 45 nhan (463 +x) = 44955
287-x:27=2015 45x(463+x)=44955
x:27=2015+287 463+x =44955:45
x:27=2302 463+x =999
x = 2302x27 x =999-463
x = 62154 x =536
2087- x chia 27 = 2015 45 x [ 463 + x ] = 44955
2087- x : 27=2015
45x<463+ x>=44955
2087 - x : 27 = 2015
x : 27 = 2087 - 2015
x : 27 = 72
x = 72 x 27
x = 1944
45 x (463 + x) = 44955
463 + x = 44955 : 45
463 + x = 999
x = 999 - 463
x = 536

Tìm x biết: 2087-x:27=2015
45x(463+x)=44955
2087 - x :27 = 2015
x : 27 = 2087 - 2015
x : 27 = 72
x = 72 x 27
x = 1944
2087 - x : 27 = 2015
x : 27 = 2087 - 2015
x : 27 = 72
x =72 x 27
x =1944
45 x ( 463 + x ) = 44955
463 + x = 44955 : 45
463 + x = 999
x = 999 - 463
x = 536
2087-x:27=2015
x:27=2087-2015
x:27=72
x =72x27
x =1944
45x(463+x)=44955
463+x=44955:45
463+x=999
x=999-463
x=536
45 nhân (463+x)=44955
Ta có: 45 x (463 + x ) = 44955
463 + x = 44955 : 45
463 + x = 999
x = 999 - 463
x = 536
45 x (463+x)=44955
=) 44955 : 45 = 463 +x
=) 999 = 463 +x
= )x = 999 - 463
=) x = 536
45 x (463+x) = 44955
=> 463+x=999 (=44955:45)
=> x=536 (=999-463)
Vậy x=536
2087-x /27=2015
2087-\(\frac{x}{27}\)=2015
\(\frac{x}{27}\)=2087-2015
\(\frac{x}{27}\)=72
x=72 . 27
x=1944
đề loại nào thế.
Kiểu 1 :\(2087-\frac{x}{27}=2015\)
Kiểu 2 : \(\frac{2087-x}{27}=2015\)
Kiểu 1 hay kiểu 2 vậy
2087-x/27=2015
Ta có: \(2087-\frac{x}{27}=2015\)
\(\Rightarrow\frac{x}{27}=2087-2015=72\)
\(\Rightarrow\frac{x}{27}=72\)
\(\Rightarrow x=27.72=1944\)
45X[463+x]=44955
=>463+x=44955:45
=>463+x=999
=>x=999-463
=>x=536
dung quen nhe moi nguoi
45 x (463+x) = 44955
=> 463 + x = 44955 : 45
=> 463 + x = 999
=> x = 999 - 463
=> x = 536
Nhìn thấy thì tiếc gì 1 Li.ke nhỉ ???

2087-x chia 27=2015
\(2087-x:27=2015\)
\(\Rightarrow\) \(x:27=2087-2015\)
\(\Rightarrow\) \(x:27=66\)
\(\Rightarrow\) \(x=66.27\)
\(\Rightarrow\) \(x=1782\)
Vậy \(x=1782\)
\(2087-x:27=2015\)
\(\Rightarrow x:27=2087-2015\)\(\Rightarrow x:27=72\Rightarrow x:72=72.27\Rightarrow x=1944\)
