Answer 1

a)x+4=10
x=10-4
x=6
b)x+1=9
x=9-1
x=8
c)x-2=-8
x=-8+2
x=-6
d)x+7=2
x=2-7
x=-5
e)x+9=-1
x=-1-9
x=-10
f)7-x=13
-x=13-7
-x=6 .(-1)
x=-6
g)9=10+x
-x=10-9
-x=1 .(-1)
x=-1

Answer 2

A)
X + 4 = 10
X = 10 - 4
X = 6

B)

X + 1 = 9
X = 9 - 1
X = 8

C)

X - 2 = -8
X = -8 + 2
X = -6

D)

X + 7 = 2
X = 2 - 7
X = -5

E)

X + 9 = -1
X = -1 - 9
X = -10

F)

7 - X = 13
X = 7 - 13
X = -6

G)

9 = 10 + X
X = 9 - 10
X = -1
