Question

a- x+5=8

b- x-4=3

c- x+6=5

d- x-7=7

e- x+9=-1

f- x+28=11

g- x-109=5

h- x-39=-79

i- x+16=10​

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 - 7 = 7.

x = 7 + 7.

x = 14.

e) x + 9 = -1.

x = -1 - 9.

x = -10.

f) x + 28 = 11.

x = 11 - 28.

x = -17.

g) x - 109 = 5.

x = 5 + 109.

x = 114.

h) x - 39 = -79.

x = -79 + 39.

x = -40.

i) x + 16 = 10.

x = 10 - 16.

x = -6.

Answer 2

Resposta:

a) x = 8 - 5

x = 3

b) x = 3 + 4

x = 7

c) x = 5 - 6

x = - 1

d) x = 7 + 7

x = 14

e) x = - 1 - 9

x = - 10

f) x = 11 - 28

x = - 17

g) x = 5 + 109

× = 114

h) x = - 79 + 39

x = - 40

i) x = 10 - 16

x = - 6
