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.

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!
