Are 2 + 6x and 2(3x + 1) equivalent
Solnce55 [7]

✳︎ ✳︎ ✳︎ ✳︎ ✳︎ ✳︎ Hello There! :)

To determine whether the two expressions are equivalent, we take the second expression and distribute 2:

2(3x+1)

6x+2=2+6x

And now we know the two expressions are equivalent. If you look, you will remember the Commutative Property that states:

a+b=b+a

In this case, a=6x and b=2.

So we know that the two expressions are equivalent.

Hope this helps! :)
