title: Inequality Constraint Ambiguity
body: <p>i've a problem in resizing a UIView with Autolayout and constraints. 
  I'd like to change the origin (less than or equal of original) and the width (greater than or equal of original) but I got this: Inequality Constraint Ambiguity</p>
  
  <p>Do you have idea for solve this?</p>
  
  <p>thanks</p>
