Year 7 Maths: Find the Missing Number An Interactive Qwizdom Lesson

6a = 30 So a = ?

4b = 28 So b = ?

c + 9 = 17 So c = ?

d + 14 = 32 So d = ?

e - 2 = 11 So e = ?

f - 5 = 15 So f = ?

100 - g = 94 So g = ?

2a + 5 = 25 So 2a = ?

2a + 5 = 25 2a = 20 So a = ?

3c + 7 = 19 So 3c = ?

3c + 7 = 19 3c = 12 So c = ?

5d - 2 = 18 So 5d = ?

5d - 2 = 18 5d = 20 d = ?

6e - 10 = 2 6e = ?

6e - 10 = 2 6e = 12 So e = ?

2f + 10 = 2 So 2f = ?

2f + 10 = 2 2f = -8 So f = ?
