what is it you are trying to accomplish?

anonymous · Answer

5m + 3n + p - 5p + 3n + 2n -m 
Rearrange them 
 5m - m + 3n + 3n + 2n +p -5p 
= 4m +8n -4p 
 = 4(m+2n-p)

anonymous · Answer

5m + 2n = 3 
-5m +3n = 7 
-------------------- 
5n = 10 
n = 10/5 
n = 2 

substitute the value of n in equation 1 
5m + 2n = 3 
5m + 2(2) = 3 
5m + 4 = 3 
5m = 3 - 4 
5m = -1 
m = -1/5 

hence, n = 2 and m = -1/5
