To add the given expression, let's follow these steps:
Step 1: Simplify the expression inside the parentheses: (x+4)
The expression (x+4) remains the same as it cannot be simplified further.
Step 2: Add 1 to the simplified expression: (x+4) + 1
The expression becomes x + 4 + 1.
Step 3: Simplify the expression inside the parentheses: 4x - 2
The expression 4x - 2 remains the same as it cannot be simplified further.
Step 4: Add the result from Step 2 to the result from Step 3: (x + 4 + 1) + (4x - 2)
Combine like terms: x + 4 + 1 + 4x - 2
Step 5: Rearrange the terms to group like terms together: (x + 4x) + (4 + 1 - 2)
Combine like terms: 5x + 3
So, the final answer in mixed number form is 5x + 3.
