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

Step-by-step explanation:
Given the expressions
Substitute 2 into 1
Answer: Time at which the meet = 10:17:24 am
Step-by-step explanation: Speed of Ivan = 12 mph
Speed of Kate = 16 mph
Total distance traveled = Initial separation = 40 miles
Ivan leaves his house at 8:00 a.m and Kate leaves her house at 9:30 a.m
If t is the time of catch up after Ivan starting, time taken by Kate is t - 1.5,
We have
Distance = Speed x Time
Total distance traveled = Distance traveled by Kate + Distance traveled by Ivan
40 = t x 12 + (t-1.5) x 16
40 = 28t - 24
28t = 64
t = 2.29 hours
So after 2.29 hours of Ivan's starting they meet,
Time = 8:00 am + 2.29 hours = 10:00 am + 0.29 x 60 minutes = 10:17am + 0.4 x 60 seconds = 10:17:24 am
Time at which the meet = 10:17:24 am
