The LCD of 3 and 4 is 12. To make 4 into 12, we multiply it by three, so 3 would also have to be multiply by 3, turning 3/4 into 9/12.

The same thing applies to 1/3, only it needs to be multiplied by 4. So it would become 4/12

9/12 - 4/12 = 5/12

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
