What property will be used to complete the first step in solving for n?

subtraction property of equality

multiplication property of equality

division property of equality

distributive property

Answer 2

Subtraction Property of Equality

Explanation:

When solving an equation for a variable (in this case n), we want to move all of the n-terms to 1 side and the non-n terms to the other side. To do this, we can subtract 5.2 from both sides to leave 2.5n by itself. The property we used to do this is the Subtraction Property of Equality which states that if you subtract a quantity from one side of an equation, you must also subtract that same quantity from the other side of the equation.
