a) x+5=0

b)x+4= -3 obs;e menos 3

c)x-2= -3 obs;e menos 3

d)7=x+1

e)0=x+4

Answer 1

a) x+5 = 0
x = -5

b) x+4 = -3
x = -3 - 4
x = -7

c) x-2 = -3
x = -3 +2
x = -1

d) 7 = x+1
7-1 = x
6 =x 

e) 0 = x+4
0-4 = x
-4 = x

Answer 2

a= x+5=0
x=-5

b= x+4= -3
x= -3-4
x= -7

c= x-2= -3
x= -3+2
x= -1

d= 7= x+1
7-1= x
6= x

e= 0= x+4
0-4= x
-4= x
