Multiplication Property of Equality

When rewriting equations it's important to make the the same operation on both sides to ensure that the equality still holds. So, if a number is multiplied to one side, the same number must be multiplied to the other side. In the equation

0.5 x = 5,

2

can be multiplied to both sides.

2 \cdot 0.5 x = 2 \cdot 5 \Leftrightarrow x = 10
