Answer:

1. X=27

2. X=2.4

3. y= 1.5

4. p=-1.33

5. X=-1.6

solution,


1. \: \: (2x)/(3) = 18 \\ \: \: or \: 2x = 18 * 3(cross \: multiplication) \\ \: \: or \: 2x = 54 \\ \: \: \: or \: x = (54)/(2) \\ \: \: \: x = 27


2. \: \: 1.6 = (x)/(1.5) \\ \: \: or \: x = 1.6 * 1.5( \: cross \: multiplication) \\ \: \: \: \: x = 2.4


3. \: \: 14y - 8 = 13 \\ \: \: \: or \: 14y = 13 + 8 \\ \: \: or \: 14 \: y = 21 \\ \: \: or \: 14 * y = 21 \\ \: \: \: or \: y = (21)/(14) \\ \: divide \: 21 \: and \: 14 \: by \: 7 \: you \: will \: get \\ \:or \: y = (3)/(2) \\ y = 1.5


4. \: \: 17 + 6p = 9 \\ \: \: or \: 6p = 9 - 17 \\ \: \: or \: 6p = - 8 \\ \: \: or \: p = ( - 8)/(6) \\ \: \: or \: p = ( - 4)/(3) \\ \: \: p = - 1.33 \\


5. \: \: (x)/(3) + 1 = (7)/(15) \\ \: or \: (x + 1 * 3)/(3) = (7)/(15) \\ \: \: or \: (x + 3)/(3) = (7)/(15) \\ \: or \: 15(x + 3) = 7 * 3( \: cross \: multiplication) \\ \: \: or \: 15x + 45 = 21 \\ \: \: or \: 15x = 21 - 45 \\ \: \: or \: 15x = - 24 \\ \: \: or \: x = ( - 24)/(15) \\ \: divide \: - 24 \: and \: 15 \: by \: 3 \\ \: or \: x = ( - 8)/(5) \\ x = - 1.6

Hope this helps ...

Good luck on your assignment..
