Question

I need to be in a session to post the picture of the problem

Answer 1

The value of x that makes the equation true is 3

`x=3`

Step-by-step explanation:

From the attached image;

Let us write the mathematical equation of the model.

The long bar means x, while the small squares have a value of 1 each.

`2x+5=11`

solving the equation we have;

`\begin{gathered} 2x+5=11 \\ 2x=11-5 \\ 2x=6 \\ \text{divide both sides by 2;} \\ (2x)/(2)=(6)/(2) \\ x=3 \end{gathered}`

Therefore, the value of x that makes the equation true is 3

`x=3`
