Question

if x=2,y=-3,z=4,find the value of 1/x -1/y-1/z+5​

Answer 1

$\pink{Given\:value\:of\:x\:=\:2\:,\;y\:=\:-\:3\:,\:z\:=\:4}$

$\large\rightarrow{\mathtt{\frac{1}{x}\:-\:\frac{1}{y}\:-\:\frac{1}{z}\:+\:5}}$

$\large\rightarrow{\mathtt{\frac{1}{2}\:-\:{\large{(\frac{1}{-\:3}) }\:-\:\frac{1}{4}\:+\:5}}}$

$\large\rightarrow{\mathtt{\frac{1\:×\:6\:-\:1\:×\:-\:4\:-\:1\:×\:3}{12}\:+\:5}}$

$\large\rightarrow{\mathtt{\frac{6\:+\:4\:-\:3}{12}\:+\:5}}$

$\large\rightarrow{\mathtt{\frac{7}{12}\:+\:5}}$

$\large\rightarrow{\mathtt{\frac{7}{12}\:+\:5\:×\:12}}$

$\large\rightarrow{\mathtt{\frac{7}{12}\:+\:60}}$

$\large\rightarrow{\mathtt{\frac{7\:+\:60}{12}}}$

$\large\rightarrow\pink{\boxed{\color{crimson}{\mathtt{\frac{67}{12}}}}}$
