In the equation 2y=18, determine which property of equality will be used to isolate the variable. Choose the best answer. A. Mul
mixer [17]

Answer:

(C) Division Property of Equality

Step-by-step explanation:

Looking at the equation 2y=18, we see that if we want to isolate y, we need to divide it by 2 - because we're multiplying it by 2, and 2 times a number divided by 2 is just the number.

The Division Property of Equality states that if we have an equation, a=b, then a\div c = b\div c.

So, that means 2y\div 2 will be equal to 18 \div 2, which is 9.

Hope this helped!
