Answer 1

Answer:

p=9/2

Step-by-step explanation:

1. 5p-15=3p-6. 2p=9. p=9/2

Answer 2

$1」5(p - 3) = 3(p - 2) \\ 5p - 15 = 3p - 6 \\ 5p - 3p = - 6 + 15 \\ 2p = 9 \\ p = \frac{9}{2}$

$2」5(z + 3) = 4(2z + 1) \\ 5z + 15 = 8z + 4 \\ 8z - 5z = 15 - 4 \\ 3z = 11 \\ z = \frac{11}{3}$

$3」15(x - 1) + 4(x + 3) = 2(7 + x) \\ 15x - 15 + 4x + 12 = 14 + 2x \\ 15x + 4x - 2x = 14 + 15 - 12 \\ 17x = 14 + 3 \\ 17x = 17 \\ x = \frac{17}{17} \\ x = 1$

$4」3(5z - 7) + 2(9z - 11) = 4(8z - 7) - 111 \\ 15z - 21 + 18z - 22 = 32z - 28 - 111 \\ 15z + 18z - 32z = - 28 - 111 + 21 + 22 \\ 33z - 32z = - 28 - 111 + 43 \\ z = - 139 + 43 \\ z = - 96$

$5」8(x - 3) - (6 - 2x) = 2(x + 2) - 5(5 - x) \\ 8x - 24 - 6 + 2x = 2x + 4 - 25 + 5x \\ 10x - 2x - 5x = 4 - 25 + 24 + 6 \\ 10x - 7x = 4 - 25 + 30 \\ 3x = 4 + 5 \\ 3x = 9 \\ x = \frac{9}{3} \\ x = 3$

$6」3(n - 4) + 2(4n - 5) = 5(n + 2) + 16 \\ 3n - 12 + 8n - 10 = 5n + 10 + 16 \\ 3n + 8n - 5n = 10 + 16 + 12 + 10 \\ 11n - 5n = 48 \\ 6n = 48 \\ n = \frac{48}{6} \\ n = 8$
