No, it is not a perfect cube. A perfect cube is a number that is obtained when you cube an integer. For example, 8 (cube of 2), 27 (cube of 3) and 64 (cube of 4). Since -3 cannot be obtained by cubing an integer, it is not a perfect cube.

$2x-5= - 20$

$
2x=-20+5
 
$ $Add \ 5 \ to \ both \ sides
$

$2x=-15

 
$

$x=- \dfrac{15}{2}$ $Divide \ both \ sides \ by \ 2$
