x : 142 + 457 = 625
x - 16,7 + 8,6 = 16,9
( x - 1\(\frac{3}{4}\)) x : 2\(\frac{1}{4}\)= \(\frac{5}{3}\)
\(\frac{x}{142}+457=625\)
\(\frac{x}{142}=168\)
\(\Rightarrow x=168.142\)
\(\Rightarrow x=23856\)
vậy \(x=23856\)
\(x-16,7+8,6=16,9\)
\(x=16,9-8,6+16,7\)
\(x=25\)
vậy \(x=25\)
\(\left(x-1\frac{3}{4}\right)x:2\frac{1}{4}=\frac{5}{3}\)
\(\left(x-\frac{7}{4}\right)x:\frac{9}{4}=\frac{5}{3}\)
\(x^2-\frac{7}{4}x=\frac{5}{3}.\frac{9}{4}\)
\(x^2-\frac{7}{4}x=\frac{15}{4}\)

x × 8 = 25.6
x : 7,5 = 27,44
( x : 142 ) + 457 = 625
Giúp tớ nhé!
X x 8 = 25.6
X = 25.6 : 8
X = 3.2
X : 7.5 = 27.44
X = 27.44 x 7.5
X = 205.8
(X : 142 ) + 457 = 625
X : 142 = 625 - 457
X : 142 = 168
X = 168 x 142
X = 20 832
