4(u+3)+3u=-2
distribute: 4u+12+3u=-2
simplify: 7u+12=-2
isolate the variable: 7u=-14
divide: u=-2
check answer: 4(-2+3)+3(-2)=-2
-8+12-6=-2
-2=-2
therefore, u= -2

Answer:
11. 10/9 = 80/72
12. 8/12 = 72/108
13. 22/99 = 2/9
14 4 41/123 = 4 1/3
15. 84/840 = 1/10
16. 6/14 vs 3/7 (cross multiply numerators and denominators)
42 vs 42
Therefore 6/14 = 3/7
17. 2/3 vs 5/7 (cross multiply numerators and denominators)
14 vs 15
Therefore 2/3 < 5/7
18. 1/5, 1/2, 1/4 (Change to decimals then compare)
.20 .50 .25
Therefore increasing order is 1/5, 1/4, 1/2
19. 5/7, 5/6, 7/9 (Change to decimals then compare)
.71 .83 .77
Therefore increasing order is 5/7, 7/9, 5/6

Answer: 108
Step-by-step explanation:
Given that the ratio of men to women is 5:4.
Let x be the total employees then,
Men = x*5/9
135 = x*5/9
x = 135*9/5
The total employees are 243
Women are 243 - 135 = 108
