Question

2) Resolva as seguintes equações:
a) x + 5 = 8
b) x - 4 = 3
c) x + 6 = 5
d) x-3 = -7
e) x + 9 = -1
f) x + 28 = 11​

Answer 1

a) x + 5 = 8

x = 8 - 5

x = 3

b) x - 4 = 3

x = 3 + 4

x = 7

c) x + 6 = 5

x = 5 - 6

x = - 1

d) x - 3 = -7

x = - 7 + 3

x = - 4

e) x + 9 = -1

x = - 1 - 9

x = - 10

f) x + 28 = 11​

x = 11 - 28

x = - 17
