3x + 4 = 10, then 3x = 6. This is an illustration of which property?

a) Multiplication property of equality
b)Substitution
c)Commutative
d)Subtraction property of equality

Respuesta :

3x + 4 = 10..subtract 4 from both sides
3x = 6....subtraction property of equality
The correct answer is D. subtraction property of equality.

The reason is that you subtract 4 on BOTH sides of an equation, which makes the two sides still equivalent.

Hope this helps.
