Find the value of a in the arithmetic operations shown in the table.
Understand the Problem
The question is asking to determine a value based on the operations shown in the table. Specifically, it appears to be solving for an unknown variable represented with 'a' in a series of arithmetic operations where certain results are already provided.
Answer
The value is 2.
Answer for screen readers
The final answer is 2.
Steps to Solve
- Identifying the first equation
From the table, we can see that the first operation is represented as follows: $$ 5 - a = 2 $$
- Solving the first equation for 'a'
To isolate $a$, we'll move $a$ to one side and the other terms to the opposite side: $$ 5 - 2 = a $$
- Calculating the value of 'a'
Now, we calculate: $$ a = 5 - 2 = 3 $$
- Identifying the second equation
The second operation in the table is represented as follows: $$ 3 + a = 4 $$
- Solving the second equation for 'a'
Now, we solve for $a$: $$ a = 4 - 3 $$
- Calculating the value of 'a'
We calculate: $$ a = 4 - 3 = 1 $$
- Identifying the third equation
The third operation in the table is: $$ a + 1 = ? $$
- Substituting the value of 'a'
Now we substitute $a = 1$ into the third equation: $$ 1 + 1 = ? $$
- Calculating the final result
Now, let’s calculate: $$ ? = 1 + 1 = 2 $$
The final answer is 2.
More Information
This problem involves basic arithmetic operations. By isolating the variable 'a' through each equation, we find the required values step-by-step. The process demonstrates how to solve linear equations by applying arithmetic principles.
Tips
- Neglecting to properly isolate the variable when solving equations.
- Mixing up addition and subtraction, which can lead to incorrect results.
