Answer 1

Resposta:

a) X + 5 = 8

x = 3.

b) X − 4 = 3

x = 7.

c) x + 6 = 5

x = -1.

d) x − 7 = −7

x = 0.

e) x + 9 = −1

x = -10.

f) x + 28 = 11

x = -17.

g) x − 109 = 5

x = 114.

h) x − 39 = −79

x = -40.

i) 10 = x + 8

x = 2.

j) 15 = x + 20

x = -5.

k) 4 = x − 10

x = 14.

l) 7 = x + 8

x = 15.

m) 0 = x + 12

x = -12.

n) −3 = x + 1

x= -4.

Espero ter ajudado em alguma coisa.

Boa tarde.
