a) x + 9,44 = 18,36
x = 18,36 - 9,44
x = 8,92
b) 2012 : x + 23 = 526
2012 : x = 526 - 23
2012 :x = 503
x = 2012 : 503
x = 4
a)x+9,44=18,36
x=18,36-9,44
x=8,92
b)2012:x+23=526

a)2012÷x+23=526
2012 : x = 503
x = 4
b)1/2÷x+9,44=18,36
1/2 : x = 8,92
x = 25/446
c)x-3/4=6×1/24
x - 3/4 = 1/4

\(\frac{3}{8}.x+1=\frac{7}{8}\) \(2012:x+23=526\)
\(\Leftrightarrow\frac{3}{8}.x=\frac{7}{8}-1\) \(\Leftrightarrow2012:x=503\)
\(\Leftrightarrow\frac{3}{8}.x=\frac{-1}{8}\) \(\Leftrightarrow x=4\)
\(\Leftrightarrow x=\frac{-1}{3}\)
Câu a bạn viết lại đề đi nha khó nhìn quá
Câu b
2012 : x + 23= 526
2012 : x = 526-23
2012: x=503
x=2012 : 503
x =4

a) 2012 : x + 23 = 526
=> 2012 : x = 526 - 23 = 503
=> x = 2012 : 503 = 4
c) (x - 1/2) x 5/2 + 1/2 = 7/4
(x - 1/2 ) x 5/2 = 7/4 - 1/2 = 5/4
=> x - 1/2 = 5/4 : 5/2 = 1/2
=> x = 1/2 + 1/2 = 1
=> x = 1
a, 2012 : x + 23 = 526
2012 : x = 526 - 23
2012 : x = 503
x = 2012 : 503
x = 4
b , ( x - 1/2 ) x 5/2 + 1/2 = 7/4
( x - 1/2 ) x 5/2 = 5/4
x - 1/2 = 5/4 : 5/2
x -1/2 = 1/2
x = 1/2 + 1/2
x = 1

= 526 x 637 + 637 - 189 / 526 x 637 + 448
= 526 x 637 + 448 / 526 x 637 + 448
= 1

A = ( 3 + 9 + 20 + 28 + 38 + 1 + 1 ) x 2012
A = 100 x 2012
A = 201200
A = 3 x 2012 + 9 x 2012 + 20 x 2012 + 28 x 2012 + 38 x 2012 + 2012 + 2012
A = 2012 x ( 3 + 9 + 20 + 28 + 38 + 1 + 1 )
A = 2012 x 100
A = 201200
