Quizplus · Accepted Answer

To solve the equation t - 8 = 10, we need to isolate t on one side of the equation. We can do this by adding 8 to both sides:

t - 8 + 8 = 10 + 8
t = 18

Therefore, the solution is t = 18. We can check this by substituting t = 18 back into the original equation:

t - 8 = 10
18 - 8 = 10
10 = 10

Since the left-hand side of the equation is equal to the right-hand side, we have verified that t = 18 is the correct solution. Therefore, the best choice is D, t = 18. To solve the equation, add 8 to both sides: 
t - 8 + 8 = 10 + 8 
t = 18

To check the solution, substitute 18 for t in the original equation: 
18 - 8 = 10 
10 = 10

The equation is true, so t = 18 is the correct solution. Therefore, the best choice is D.
