Step-by-step explanation:

Your question isn't complete but let me help out.

You said that you thought of number J, and then subtracted half of it from 34. This can be mathematically written as:

= 34 - (J/2)

Let's reframe the question and assume that you thought of a number J, and then subtracted half of it from 34 and the answer you get is 12. To find J goes thus:

You subtract half of J from 34 and equate it to 12. This will be:

34 - (J/2) = 12

Collect like terms

34 - 12 = J/2

22 = J/2

J = 22 × 2

J = 44

In this scenario, J = 44. We can check to confirm.

Check: 34 - (J/2)

= 34 - (44/2)

= 34 - 22

= 12
