7x+1 is equal to 1+7x.

According to the commutative property of addition, it doesn't matter what order you add things in, you'll still get the same answer.

Hope this helps!

It’s equivalent. You are using the commutative property. If you switch the numbers to opposite sides in addition or multiplying, it will be equal.
