Statistical question--

A statistical question is one which is based over the data which is sampled or collected such that there is a variability in the data.

Here the first three questions i.e.

Question 1How old am I?

Question 2How old is the teacher?

Question 3How old will I be after my next birthday?

are not based over the sample these are based over  a individual and not over the data or population. Hence, they are invalid.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
