Answer 1

Vamos lá, as contas são bem simples!

a) x+5= 7
x= 7-5
x= 2

b) x+9= 2
x= 2-9
x= -7

c) 6+x= 9
x= 9-6
x= 3

d) x-7= 3
x= 3+7
x= 10

e) x+4= 10
x= 10-4
x= 6

f) x+1= 9
x= 9-1
x= 8

g) x-2= 8
x= 8+2
x= 10

h) x+3= 3
x= 3-3
x= 0

i) x-9= -7
x= -7+9
x= 2

j) -10+x= -8
x= -8+10
x= 2

k) -8+x= -3
x= -3+8
x= 5

Bons estudos! ;)
