A) X+4 =10
B) X + 1 = 9
C) X- 2 = 8
D) X+3 = 3
E) X+ 101 = 300
F) X- 279= 237
G) X+ 7 = 2
H) X + 9 = - 1
I ) X - 8= - 10
J) 10 + X = 15
L) 17 + X = 13
M) 128 + X = 900

Answer 1

A) X+4 =10  , X = 10 - 4 = 6

B) X + 1 = 9, X = 9 - 1 = 8

C) X- 2 = 8, X = 8 + 2 = 10

D) X+3 = 3, X = 3 - 3 = 0

E) X+ 101 = 300, X = 300 - 101 = 199

F) X- 279= 237, X = 237 + 279 = 516

G) X+ 7 = 2, X = 2 - 7 = -5

H) X + 9 = - 1  , X = -1 - 9 = -10

I ) X - 8= - 10, X = -10 + 8 = -2

J) 10 + X = 15, X = 15 - 10 = 5

L) 17 + X = 13, X = 13 - 17 = -4

M) 128 + X = 900, X = 900 - 128 = 772
