On the basis of projections for the year 2022, the number of women and men in the workforce (in millions) can be estimeted by Women: -7x+16y=1070 Men: -5x+10y=759 where x=14 correspondds to the year 2014. According to these models, will the number of women in the workforce equal the number of men during the time period from 2014 to 2022 (that is, 14 ≤ x ≤22)?
