Question 22902
If {{{a/b=c/d}}}, then {{{ad=bc}}}.


In the same way:

If {{{(p+3)/2=(p-1)/6}}}, then {{{6(p+3) = 2(p-1)}}}

6p+18 = 2p-2


Subtract 2p from each side:
4p +18= -2


Subtract 18 from each side:
4p+18-18 = -2 -18
4p=-20


Divide both sides by 4: 
p=-5


Check the answer:

{{{(p+3)/2=(p-1)/6}}}
{{{(-5+3)/2 = (-5-1)/6}}}
{{{(-2)/2=(-6)/6}}}
{{{-1=-1}}}

It checks!
