Solve for p. 20p + -5p – -17 = -13
STatiana [176]
20p + -5p - -17 = -13 

20p + -5p - -17 = -13:p  |Solve \  for \ p| 

20p-5p+17=-13 


15p+17=-13
 
 


15p=-13-17
 
  |Subtract \ 17 \ from \ both \ sides| 


15p=-30
 
 


15p/15=-30/15
 
  |Divide  \ both \ sides \ by \ 15| 


p=-2

PLEASE HELP! 40 POINTS

I'd start with setting up the equations. Calling x the number of students in most popular country 1, and y in country 2.

x + y = 44740

x - y = 5672

now solve for x1 and x2. You can subtract second from first:

0 + 2y = 39068

y = 19534

so

x = 5672 + 19534 = 25206

Add a sentence to answer it in words.
