Answer:
-14x - 9y = 6
Step-by-step explanation:
If we subtract the second equation from the first, we will get this setup:
(-7x - y) - (7x + 8y) = -14x - 9y
0 - (-6) = 6
So the resulting equation -14x - 9y = 6
Answer:
Phoebe:180
Polly:30
Andy:60
Step-by-step explanation:
Shorten them as
Polly:x
Phoebe:y
Andy:z
y=3z
z=2x
y=6x
Subsituting:x+y+z----->3x+y----->9x
9x=270 x=30 y=180 z=60
