what is the property of -2y = 18? After solving?

Answer 1

Hi Lindsey,

Based on the informative you have provided, the property of -2y = 18 would be the Multiplicative Identity Property (also known as the Multiplication Property of Equality).

The Multiplicative Identity Property features the following formula: a x b = b x c.

In order to solve unknown variables in algebraic equations containing the Multiplicative Identity Property (or the Multiplication Property of Equality), you divide both sides of the equation by the whole positive number or negative number multiplied by the unknown variable.

In the case of the above equation, divide both sides of the equation by -2. 18/-2 = -9.

So y = -9.
