a, Để phân số trên là số nguyên thì \(7⋮x-3\)

\(\Rightarrow\)\(x-3\inƯ\left(7\right)\)

\(\Rightarrow\)\(x-3\in\left\{1;-1;7;-7\right\}\)

\(\Rightarrow\)\(x\in\left\{4;2;10;-4\right\}\)

b, Để phân số trên là số nguyên thì \(x-7⋮x+2\)

\(\Rightarrow\)\(\left(x+2\right)-9\)\(⋮x+2\)

Vì \(x+2\)\(⋮x+2\)

nên \(9\)\(⋮x+2\)

\(\Rightarrow\)\(x+2\in\left\{1;-1;3;-3;9;-9\right\}\)

\(\Rightarrow\)\(x\in\left\{-1;-3;1;-5;7;-11\right\}\)

c, \(\frac{2x-3}{x+2}=\frac{2\left(x+2\right)-7}{x+2}=2-\frac{7}{x+2}\)

Để phân số trên là số nguyên thì \(7⋮x+2\)

\(\Rightarrow\)\(x+2\inƯ\left(7\right)\)

\(\Rightarrow\)\(x+2\in\left\{1;-1;7;-7\right\}\)

\(\Rightarrow\)\(x\in\left\{-1;-3;5;-9\right\}\)
