it's interpreted as 28 - 21 = 7
harvey can mesure 3 qrt in the 3 qrt container and 1 qrt in the 5qrt container
X = -6y - 12
4x + 5y =-39
4x + 5y = -39
-4(-6y - 12) + 5y = -39
-4(-6y) + 4(12) + 5y = -39
24y + 48 + 5y = -39
29y + 48 = -39
29y = -87
y = -3
x = -6y - 12
x = -6(-3) - 12
x = 28 - 12
x = 6
(x, y) = (6, -3)
Apply Pythagoras:
length = sqrt( (10--4)² + (6-3)² ) = sqrt(205)
