<em>Bringing</em><em> </em><em>all</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>together</em><em> </em><em>and</em><em> </em><em>constants</em><em> </em><em>together</em><em>:</em>
Perimeter of triangle= 2x +x +3x -6 +8 +1
<em>Simplify:</em>
Perimeter of triangle= 6x +3
