What is the value of 3x + 5 when x = 4?

Explanation:
To find the value of the expression \(3x + 5\) when \(x = 4\), you need to substitute \(4\) in place of \(x\). Start by substituting: \[ 3(4) + 5 \] Next, calculate \(3 \times 4\): \[ 3 \times 4 = 12 \] Now add \(5\) to \(12\): \[ 12 + 5 = 17 \] Thus, the value of \(3x + 5\) when \(x = 4\) is \(17\). This confirms that the correct answer reflects the calculation accurately, leading to the conclusion that the solution is indeed \(17\).

To find the value of the expression (3x + 5) when (x = 4), you need to substitute (4) in place of (x).

Start by substituting:

[

3(4) + 5

]

Next, calculate (3 \times 4):

[

3 \times 4 = 12

]

Now add (5) to (12):

[

12 + 5 = 17

]

Thus, the value of (3x + 5) when (x = 4) is (17). This confirms that the correct answer reflects the calculation accurately, leading to the conclusion that the solution is indeed (17).
