Jack got the expression 7x + 1 and then wrote his answer as 1 + 7x. Is his answer an equivalent expression? How do u know? Explain using extended vocabulary

Sagot :

Yes, it is an equivalent expression because even though you move two pieces of an equation it will still equal the same thing, unless there are parentheses involved.
eah
7x + 1    is composed by    + 7x       and       + 1

1 + 7x     is composed by      + 1          and      + 7x


So
7x + 1 = 1 + 7x
