Answer:
hi if you want to solve fore x and y there must be 2 equations .
Step-by-step explanation:
so that you could solve them simultaneously
-7x + 2y = 4
here 2y - 4 = 7x
( 2y -4)/7 = x
Answer:
B -4x+28 = 8
Step-by-step explanation:

28 - 4*x = 8
Rearranging to match an equation listed
-4x+28 = 8
Because of the pressure differences.
