For which values of p and q does the following equation have infinitely many solutions?
Licemer1 [7]
The equation:
p x + q = 46 x + 23
p x - 46 x = 23 - q
x ( p - 46 ) = 23 - q
x = ( 23 - q ) / ( p - 46 )
This equation has infinitely many solutions for :
23 - q = 0  and  p - 46 = 0
or:  q = 23  and  p = 46
Answer : A ) p = 46 & q = 23
