5 + 4 - 5 - 1

Using PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right), we can solve the expression step by step:

1. 5 + 4 = 9 (Addition)
2. 9 - 5 = 4 (Subtraction)
3. 4 - 1 = 3 (Subtraction)

Therefore, the final answer is 3.
2x - 2 = 14

To solve the equation 2x - 2 = 14, we can isolate the variable x using the following steps:

1. First, add 2 to both sides of the equation to isolate the term 2x:
2x - 2 + 2 = 14 + 2
2x = 16

2. Next, divide both sides of the equation by 2 to solve for x:
(2x)/2 = 16/2
x = 8

Thus, the solution to the equation 2x - 2 = 14 is x = 8.
