Answer:

2x + 4 is 14

Step-by-step explanation:

Given:

John owns x books

Sue owns 4 more than twice the amount John owns = 2x + 4

To find:

the value of 2x + 4 when x = 5

To determine the value, we will substitute 5 for x in the expression:


\begin{gathered} 2x\text{ + 4 = 2\lparen5\rparen + 4} \\ 2(5)\text{ = 10} \\ 2\left(5\right)+4\text{ = 10 + 4} \\ 2\left(5\right)+4\text{ = 14} \end{gathered}

If x is 5 then 2x + 4 will be 14
