Question

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

Answer 1

Answer:

The value of x that makes the equation true is 3

$x=3$

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;

$\begin{gathered} 2x+5=11 \\ 2x=11-5 \\ 2x=6 \\ \text{divide both sides by 2;} \\ \frac{2x}{2}=\frac{6}{2} \\ x=3 \end{gathered}$

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

$x=3$
