Respuesta :

The Solution.

It expression we are working on is given to be

[tex]2x=22[/tex]

When both sides were multiplied by 1/2, we have

[tex]\frac{1}{2}(2x)=\frac{1}{2}(22)[/tex]

The justification is: Multiplicative property of equality.

Thus, the answer is the multiplicative property of equality.
