Hi!
<h3>Divide by -10 on both sides. </h3>
-10x/-10 < -100/-10
<h3>The inequality sign flips because we are dividing by a negative number. </h3>
<u>x > 10</u>
<h2>The answer is A x > 10</h2>
Hope this helps! :)

AB+BC+AC-12=AC+CD+AD
AB+BC-12=CD+AD
AB+BD+CD-12=CD+AD=BD
AB+BD-12=0
AB=12cm
I’m a little confused by the question and the problem, is there a picture of the problem you could add?
