Answer:
oh.
Step-by-step explanation:
3y + 4 = 11y
(take away 3y from both sides)
4 = 8y
(divide by 8 on both sides)
0.5 = y
y = 0.5
Answer:
y>-2
Step-by-step explanation:

GIVE BRAINLEIST WHEN U CAN PLEASE
Let x be the mass of the paperbacks and y be the mass of the textbook.
20x + 9y = 44.4 ----------- (1)
25x + 10y = 51 -------------(2)
(1) x 10:
200x + 90y = 444 --------(1a)
(2) x 9:
225x + 90y = 459 --------(2a)
(2a) - (1a):
25x = 15
x = 0.6 -------- sub into (1)
20 (0.6) + 9y = 44.4
12 + 9y = 44.4
9y = 44.4 - 12
9y = 32.4
y = 3.6
So the paperback's mass is 0.6 pounds and textbook is 3.6 pounds
