Answer 2

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)
$x - 39 = - 79 \\ x = - 79 + 39 \\ x = - 40$
i)
$x - 10 = + 8 \\ x = 8 + 10 \\ x = 18$
j)
$x + 15 = 20 \\ x = 20 - 15 \\ x = 5$
k)
$x - 4 = - 10 \\ x = - 10 + 4 \\ x = - 6$
l)
$x - 7 = + 8 \\ x = + 8 + 7 \\ x = 15$
m)
$x - 10 = 12 \\ x = 12 + 10 \\ x = 22$
n)
$x - 3 = + 10 \\ x = + 10 + 3 \\ x = 13$
