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?​

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 = 0

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 = 118

Answer 2

Explicação passo-a-passo:

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=0

e) x+9= -1

x=-1+9

x=8

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
