Answer: Part A: 44/30 or 1 and 7/15. Part B: 17/30
Step-by-step explanation: Convert all the fractions to a denominator of 30 and do the adding and subtracting.
3 x + 3 (x + y)
3 (2 x + y)
6 x + 3 y
y = -2 x
y = -2 x (3 (x + y) + 3 x) = 6
(3 (x + y) + 3 x) = 3
(3 x + 3 (x + y)) dx = 3 (x^2 + x y) +
(x^2 + y^2<R^2)(3 (x + y) + 3 x) dx dy = 0
(3 x + 3 (x + y)) dy dx = 0
