G)120

H)4

Answer 2

Resposta:

a) x + 17 = 99

x = 99 - 17

x = 82

b) m - 11 = 67

m = 67 + 11

m = 78

c) 5y + 20 = 40

5y = 40 - 20

5y = 20

y = 20/5

y = 4

d) 9p + 18 = 45

9p = 45 - 18

9p = 27

p = 27/9

p = 3

e) 100x + 100 = 300

100x = 300 - 100

100x = 200

x = 200/100

x = 2

f) t - 34 = 29

t = 29 + 34

t = 63

g) 2x + 125 = 275

2x = 275 - 125

2x = 150

x = 150/2

x = 75

h) 2y + 8 = 12

2y = 12 - 8

2y = 4

y = 4/2

y = 2
