Answer:
24x - 12
Step-by-step explanation:
6x + 4 + 10x - 9 + 8x - 7

Answer:Kimo is 17 years old and Jennifer is 13 years old.
Step-by-step explanation:
Let x represent Kimo's current age.
Let y represent Jennifer's current age.
Nine years ago, Kimo was twice as old as Jennifer was then. It means that
x - 9 = 2(y - 9)
x - 9 = 2y - 18
x = 2y - 18 + 9 = 2y - 9
In four years, Jennifer will be the same age that Kimo is now. It means that
x = y + 4 - - - - - - - - - 1
Substituting x = 2y - 9 into equation 1, it becomes
2y - 9 = y + 4
2y - y = 4 + 9
y = 13
x = 2y - 9 = 2 × 13 - 9
x = 17
Answer:
Below
Step-by-step explanation:
● 2 ( x-1) - 5 (x+9)
● 2x - 1 - 5x - 45
● 2x -5x -1 - 45
● - 3x - 46
● 5x - 5 - 7x + 14
● 5x - 7x - 5 + 14
● -2x + 9
