Question

me ajudem gente urgente
$6)x + 1 - 2 = + 1$
$7)x - 9 = - 7$
$8)x - 9 + 6 = - 3$
$9)x + 6 - 3 = - 5$
$10)x - 7 - 5 = - 6$

Answer 1

6) x + 1 - 2 = 1

   x = 1 -1 + 2

   x = 2

7) x - 9 = - 7

    x = - 7 + 9

    x = 2

8) x - 9 + 6 = - 3

   x = - 3 - 6 + 9

   x = 0

9) x + 6 - 3 = - 5

   x = - 5 - 6 + 3

   x = - 8

10) x - 7 - 5 = - 6

    x = - 6 + 7 + 5

   x = 6

Answer 2

6) x+1-2=1
x-1=1
x=1+1
x=2

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

8)x-9+6= -3
x-3=-3
x=-3+3
x=0

9)x+6-3= -5
x+3= -5
x= -5-3
x= -8

10) x-7-5= -6
x-12=-6
x= -6+12
x= 6
