Answer: the solution is t = 5.8
Explanation:
The equation that we have here is:
t+18.1=23.9
Where i guess you want to solve it for t:
The first step would be isolating t in one side of the equation:
for this, we subtract 18.1 in both sides, and get:
(t + 18.1) - 18.1 = (23.9) - 18.1
t = 23.9 - 18.1 = 5.8
t = 5.8
