Answer:
The value of x that makes the equation true is 3
[tex]x=3[/tex]
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.
[tex]2x+5=11[/tex]
solving the equation we have;
[tex]\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}[/tex]
Therefore, the value of x that makes the equation true is 3
[tex]x=3[/tex]
