t - (-4) = 18

t = 18 - 4
t = 14

To solve the equation t - (-4) = 18, you can follow these steps:

Step 1: Simplify the expression on the left-hand side of the equation. The subtraction of a negative number is equivalent to adding a positive number. Therefore, t - (-4) can be rewritten as t + 4.

So, the equation becomes t + 4 = 18.

Step 2: Solve for t. To isolate the variable t, you need to undo the addition of 4. Since +4 was added to t, you need to perform the opposite operation, which is subtraction. Subtract 4 from both sides of the equation:

t + 4 - 4 = 18 - 4

This simplifies to:

t = 14.

So, the solution to the equation is t = 14.
