If x = 2, what is the result of simplifying 4x + x - 3?

Explanation:
To simplify the expression \(4x + x - 3\), you first combine the like terms. The terms \(4x\) and \(x\) are both multiples of \(x\), so you can add them together: \[ 4x + x = 4x + 1x = 5x \] This simplifies the expression to: \[ 5x - 3 \] Next, you substitute the value of \(x\) with 2, since the question states that \(x = 2\): \[ 5(2) - 3 \] Calculate \(5(2)\): \[ 10 - 3 \] Finally, perform the subtraction: \[ 10 - 3 = 7 \] Therefore, the final result after simplifying and substituting is 7. This means the correct answer is indeed 7, confirming that combining like terms and substituting the value appropriately leads to the correct outcome.

To simplify the expression (4x + x - 3), you first combine the like terms. The terms (4x) and (x) are both multiples of (x), so you can add them together:

[

4x + x = 4x + 1x = 5x

]

This simplifies the expression to:

[

5x - 3

]

Next, you substitute the value of (x) with 2, since the question states that (x = 2):

[

5(2) - 3

]

Calculate (5(2)):

[

10 - 3

]

Finally, perform the subtraction:

[

10 - 3 = 7

]

Therefore, the final result after simplifying and substituting is 7. This means the correct answer is indeed 7, confirming that combining like terms and substituting the value appropriately leads to the correct outcome.
