Question

Which values for x and y make the statement (x + 5)(y - 6) = 0 true?

x = 5, y = -6

x = 5, y = 6

x = -5, y = 6

x = -5, y = -6

Answer 1

                             $||Solving \ for \ x. ||$  

$(x + 5)(y - 6) = 0$ 

$(x + 5)(y - 6) = 0 :x$

$x+5=0$  $|Divide \ both \ sides \ by \ y-6|$ 

$x=-5$  $|Subtract \ 5 \ from \ both \ sides|$

                           $||Solving \ for \ y. ||$ 

$y-6=0$  $|Divide \ both \ sides \ by \ x+5|$ 
 
$y=6$ 

$Solution =\ \textgreater \ x = -5, y = 6$
