                             [tex]||Solving \ for \ x. ||[/tex]  

[tex](x + 5)(y - 6) = 0 [/tex] 

[tex](x + 5)(y - 6) = 0 :x[/tex]

[tex] x+5=0 [/tex]  [tex]|Divide \ both \ sides \ by \ y-6|[/tex] 

[tex] x=-5 [/tex]  [tex] |Subtract \ 5 \ from \ both \ sides|[/tex]

                           [tex]||Solving \ for \ y. ||[/tex] 

[tex] y-6=0 [/tex]  [tex]|Divide \ both \ sides \ by \ x+5|[/tex] 
 
[tex] y=6 [/tex] 

[tex]Solution =\ \textgreater \ x = -5, y = 6[/tex]
