\(x:\left[\left(1800+600\right):30\right]=560:\left(315-35\right)\)
\(x:\left[2400:30\right]=560:280\)
\(x:80=2\)
\(x=2\times80\)
\(x=160\)
\(X:80=560:280\)
\(X:80=2\)
\(X=80.2=160\)
\(x:\left[\left(1800+600\right):30\right]=560:\left(315-35\right)\)
\(\Rightarrow x:\left[2400:30\right]=560:280\)
\(\Rightarrow x:80=2\)
\(\Rightarrow x=2\times80\)
\(\Rightarrow x=160\)
Vậy x = 160
