Question 24132
<p>I didn't learn how to solve these until university would you believe! They couldn't be easier once you know how to deal with them though.<p>

<p>As I'm sure you know, the absolute value function gives you back it's argument without the sign. So if {{{abs(x)=5}}} then either {{{x=5}}} or {{{-x=5}}}. Applying the same idea to your question 1, we get two equations:</p>

{{{2(4-4x)+4=3}}}

<p>and</p>

{{{-2(4-4x)-4=3}}}

<p>Using the super automatic equation solver thingy, we get:</p>

*[invoke explain_simplification "2(4-4x)+4=3"]

<p>and</p>

*[invoke explain_simplification "-2(4-4x)-4=3"]

<p>Don't forget to put your answers back in to check!</p>

<p>Now you know how to do the first problem, have another go at the second one again yourself, but don't forget the really imporant rule:</p>

<p><font color="#ff0000">When you multiply an inequality by a negative number you must reverse the sign.</font></p>

<p>I've forgotton to do that far too many times</p>

<p>Hope that helps</p>
