Someone pls help . Thank you sm !!

Answer 1

The last 2 are 100 I’m not sure about the first one

Answer 2

• 28 = -3k + 7

28 - 7 = -3k

21 = -3k

21/-3 = k

k = -7

• 1/5 x - 17 = 3

x/5 = 3 + 17

x/5 = 20

x = 5*20

x = 100

• 82 = 7/10 G + 12

82 - 12 = 7G/10

70 = 7G/10

70*10 = 7G

700 = 7G

700/7 = G

G = 100
