Ta có: x - 3|x + 5| = 7
=> 3|x + 5| = x - 7
\(\Rightarrow\orbr{\begin{cases}3\left(x+5\right)=x-7\\3\left(x+5\right)=7-x\end{cases}\Rightarrow\orbr{\begin{cases}3x+15=x-7\\3x+15=7-x\end{cases}}}\)
\(\Rightarrow\orbr{\begin{cases}2x=-22\\4x=-8\end{cases}\Rightarrow\orbr{\begin{cases}x=-11\\x=-2\end{cases}}}\)
Vậy x = -11 , x = -2

\(\frac{x}{7}=\frac{x+16}{35}\)
\(\Leftrightarrow x\cdot35=7\left(x+16\right)\)
\(\Leftrightarrow35x=7x+112\)
\(\Leftrightarrow35x-7x=112\)
\(\Leftrightarrow28x=112\)
\(\Leftrightarrow x=4\)
Vậy x = 4
\(\frac{8}{x}=\frac{7}{x-16}\)
\(\Leftrightarrow8\left(x-16\right)=x\cdot7\)
\(\Leftrightarrow8x-128=7x\)
\(\Leftrightarrow8x-7x=128\)
\(\Leftrightarrow x=128\)
Vậy x = 128
