Step-by-step explanation:
Answer:
<em>-1/2 </em>
Step-by-step explanation:
if you divide -2 by three u get -0.6666666666666...forever
and when u divide -1 by 2 u get -0.5... they're pretty close....
7(p+3q) cross multiply out, so now you have 7p+21q. This is the same thing as 7p+21q=0
Subtract 21q from both sides of the equation
7p=-21q
Divide by 7...
p=-3q
This is simplified as you can get it.
You can use a number line to understand the place values.
