Question

Jake got the expression 7x plus 1 and then wrote his answer as 1 plus 7x. Is his answer an equivalent expression? How do you know?

Answer 1

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.

Answer 2

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!
