Key Insights
To solve for $ t $, we use the principle of equality — any operation we perform on one side must be applied to the other side to maintain balance.
-
Start with the original equation:
$$
t - 8 = 4
$$ -
Add 8 to both sides to undo the subtraction of 8:
$$
t - 8 + 8 = 4 + 8
$$ -
Simplify both sides:
$$
t = 12
$$
Now the equation is solved: $ t = 12 $.

Why This Works: The Logic Behind the Solution
By adding 8 to both sides, we cancel the $-8$ on the left, leaving only $ t $:
- $ t - 8 + 8 = t $ (because $-8 + 8 = 0$)
- $ 4 + 8 = 12 $
Thus, $ t = 12 $ is the unique solution that makes the original equation true.
Real-World Applications
Understanding how to solve $ t - 8 = 4 $ is more than just algebra practice—it’s the first step toward solving real problems:
- Budgeting: If $ t $ represents your monthly allowance and you spend $8 less than your total, leaving $4 remaining, then $ t = 12 $ means your total allowance is $12.
- Time and Distance: Suppose $ t $ is a time in hours, and subtracting 8 hours gives a result 4 hours earlier; knowing $ t = 12 $ clarifies the full timeline.
