Answer:
Explanation:
1. 7e = 40
e = 40/7
3. 24(-4/3p + 4/8p = 6)
-32p + 12p = 144
-20p = 144
p = -144/20 = -72/10 = -36/5
2. 2(5/2k + 5 = 2)
5k + 10 = 4
5k = -6
k = -6/5
4. 42(5/6d - 2/7d = 5)
35d - 12d = 210
23d = 210
d = 210/23
5. 63(6/7a - 4/9a = 2/63)
54a - 28a = 2
26a = 2
a = 2/26 = 1/13
6. 60(M/5 - M/12 = 4/20)
12M - M = 12
11M = 12
M = 12/11
7. 9(8/3h = 6/9)
24h = 6
h = 6/24 = 1/6
8. 44(7/11c = 9/4)
28c = 99
c= 99/28
Extra credit:
24(3/2y + 9/4y = 11/6 - 7/8)
36y + 54y = 44 - 21
90y = 23
y = 23/90
