>Eve was created as a "helper - suitable for Adam" - see Genesis 2:18. Adam was created first - eve was second. God's design was for Adam to lead and for Eve to follow. They are "equals" in that (quoting from the link) "they were both equally created in the image of God. Neither received more of the image of God than the other. So the Bible begins with the equality of the sexes. As persons, as human beings, as spiritual beings, standing before God, men and women are absolutely equal." As to their roles, they are not equal - the man is to lead in love - the woman is to submit to that leadership.
Of course, we could instead use the first creation story in Genesis and quote 1:27:
And God created man in His own image, in the image of God created He him; male and female created He them.
