Question 75862
{{{abs(b+9)=2}}}:
<p></p>
b+9=2 --> b+9-2=0 -->b+7=0 -->b=-7
b+9=-2--> b+9+2=0 -->b+11=0 -->b=-11
<p></p>
{{{abs( -7+9 )=2) }}}--> {{{abs( 2 )=2}}}
{{{abs(-11+9)=2 }}}--> {{{abs(-2)=2}}}
<p></p>
Solution (b=-7 or b=-11)
<p></p>
Don't need to graph this. These are only 2 points for {{{abs(b+9)}}} be equal 2.
Cheers.
