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
solve and show all work
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.
To solve the expression using PEMDAS (order of operations), follow these steps:
Step 1: Parentheses (not applicable in this example)
Step 2: Exponents (not applicable in this example)
Step 3: Multiplication and Division (not applicable in this example)
Step 4: Addition and Subtraction
Start with the given expression: 5 + 4 - 5 - 1
Step 4.1: Addition
Add 5 and 4: 5 + 4 = 9
Simplified expression: 9 - 5 - 1
Step 4.2: Subtraction
Starting from left to right, subtract 5 from 9: 9 - 5 = 4
Simplified expression: 4 - 1
Continue subtracting 1 from 4: 4 - 1 = 3
Final Answer: 3
