Answer:

Award Brainliest to this answer :)

Step-by-step explanation:

1 /  p + g = 150

g - 80 = p   =>  p - g = - 80

 

2 /  Adding the equations eliminates g and gives  2p = 70, p = 35

Back substituting to the 1st Equation;  35 + g = 150  =>  g = 115  

 

3 /  No, not if the stated conditions remain.
