Question

If a = b, then a - c = b - c. This is the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ property of equality.

Answer 1

The correct answer is Subtraction property of the equality.

Explanation:

Let's recall that it's possible to perform the same operation on each side of an equivalent linear equation without changing the equality.

That's why we can add, subtract, multiply (same non-zero number) and divide (same non-zero number) the same number to each side of a linear equation and, that operation,gives us an equivalent equation .

In this particular case, we are subtracting c at both sides of the equation and this a representation of the Subtraction property of the equality.

Answer 2

Associative Property

Explanation:

Associative property involves computations that has to do with regrouping of quantities. That is simply the technique employed there.
