Question 1
1.
als x+70 = 490 dan is x +
70
- 70
= 490
-70
of x = 490 - 70 of x = 420
True
False
Question 2
2.
als x+4 = 12 dan is x +4
- 4
= 12
- 4
of x = 12 - 4 of x = 8
True
False
Question 3
3.
als x+7 = 20 dan is x +
7
- 7
= 20
- 7
of x = 20 - 7 of x = 13
True
False
Question 4
4.
als 10 +
x
= 40 dan is door commutativiteit
x
+ 10 = 40 dus x +
10
- 10
= 40
- 10
of x = 40 - 10 of x = 30
True
False

+ 4
of x = 12 + 4 of x = 16
True
False
Question 7
7.
als x-70 = 490 dan is x -
70
+ 70
= 490
+70
of x = 490 + 70 of x = 560
True
False
Question 8
8.
als x-7 = 20 dan is x -
7
+ 7
= 20
+ 7
of x = 20 + 7 of x = 27
True
False
Question 9
9.
als 10 -
x
= 40 dan is door commutativiteit
-
x

-
x +
10
- 10
= 40
- 10
of
-
x = 40 - 10 of
